Socialist calculation debate

From Wikipedia, the free encyclopedia
 
The socialist calculation debate, sometimes known as the economic calculation debate, was a discourse on the subject of how a socialist economy would perform economic calculation given the absence of the law of value, money, financial prices for capital goods and private ownership of the means of production. More specifically, the debate was centered on the application of economic planning for the allocation of the means of production as a substitute for capital markets and whether or not such an arrangement would be superior to capitalism in terms of efficiency and productivity.

A central aspect of the debate concerned the role and scope of the law of value in a socialist economy. Although contributions to the question of economic coordination and calculation under socialism existed within the socialist movement prior to the 20th century, the phrase socialist calculation debate emerged in the 1920s beginning with Ludwig von Mises' critique of socialism. The historical debate was cast between the Austrian School represented by Mises and Friedrich Hayek, who argued against the feasibility of socialism; and between neoclassical and Marxian economists, most notably Cläre Tisch (as a forerunner), Oskar R. Lange, Abba P. Lerner, Fred M. Taylor, Henry Douglas Dickinson and Maurice Dobb, who took the position that socialism was both feasible and superior to capitalism. The debate was popularly viewed as a debate between proponents of capitalism and proponents of socialism, but in reality a significant portion of the debate was between socialists who held differing views regarding the utilization of markets and money in a socialist system and to what degree the law of value would continue to operate in a hypothetical socialist economy. Socialists generally held one of three major positions regarding the unit of calculation, including the view that money would continue to be the unit of calculation under socialism; that labor-time would be a unit of calculation; or that socialism would be based on calculation in natura or calculation performed in-kind.

Debate among socialists has existed since the emergence of the broader socialist movement between those advocating market socialism, centrally planned economies and decentralized planning. Recent contributions to the debate in the late 20th century and early 21st century involve proposals for market socialism and the use of information technology and distributed networking as a basis for decentralized economic planning.

Foundations and early contributions

Karl Marx and Friedrich Engels held a broad characterization of socialism, characterized by some form of public or common ownership of the means of production and worker self-management within economic enterprises and where production of economic value for profit would be replaced by an ex ante production directly for use which implied some form of economic planning and planned growth in place of the dynamic of capital accumulation and therefore the substitution of commodity-based production and market-based allocation of the factors of production with conscious planning.

Although Marx and Engels never elaborated on the specific institutions that would exist in socialism or on processes for conducting planning in a socialist system, their broad characterizations laid the foundation for the general conception of socialism as an economic system devoid of the law of value and law of accumulation and principally where the category of value was replaced by calculation in terms of natural or physical units so that resource allocation, production and distribution would be considered technical affairs to be undertaken by engineers and technical specialists.

An alternative view of socialism prefiguring the neoclassical models of market socialism consisted of conceptions of market socialism based on classical economic theory and Ricardian socialism, where markets were utilized to allocate capital goods among worker-owned cooperatives in a free-market economy. The key characteristics of this system involved direct worker ownership of the means of production through producer and consumer cooperatives and the achievement of genuinely free markets by removing the distorting effects of private property, inequality arising from private appropriation of profits and interest to a rentier class, regulatory capture and economic exploitation. This view was expounded by mutualism and was severely criticized by Marxists for failing to address the fundamental issues of capitalism involving instability arising from the operation of the law of value, crises caused by over-accumulation of capital and lack of conscious control over the surplus product. As a result, this perspective played little to no role during the socialist calculation debate in the early 20th century.

Early arguments against the utilization of central economic planning for a socialist economy were brought up by proponents of decentralized economic planning or market socialism, including Pierre-Joseph Proudhon, Peter Kropotkin and Leon Trotsky. In general, it was argued that centralized forms of economic planning that excluded participation by the workers involved in the industries would not be sufficient at capturing adequate amounts of information to coordinate an economy effectively while also undermining socialism and the concept of worker's self-management and democratic decision-making central to socialism. However, no detailed outlines for decentralized economic planning were proposed by these thinkers at this time.

Early neoclassical contributions

In the early 20th century, Enrico Barone provided a comprehensive theoretical framework for a planned socialist economy. In his model, assuming perfect computation techniques, simultaneous equations relating inputs and outputs to ratios of equivalence would provide appropriate valuations in order to balance supply and demand.

Proposed units for accounting and calculation

Calculation in kind

Calculation in kind, or calculation in-natura, was often assumed to be the standard form of accounting that would take place in a socialist system where the economy was mobilized in terms of physical or natural units instead of money and financial calculation.

Otto Neurath was adamant that a socialist economy must be moneyless because measures of money failed to capture adequate information regarding material well-being of consumers or failed to factor in all costs and benefits from performing a particular action. He argued that relying on any single unit, whether they be labor-hours or kilowatt-hours, would be inadequate and that demand and calculations be performed by the relevant disaggregated natural units (i.e. kilowatts, tons, meters, etc.).

In the 1930s, Soviet mathematician Leonid Kantorovich demonstrated how an economy in purely physical terms could use determinate mathematical procedure to determine which combination of techniques could be used to achieve certain output or plan targets.

Debate on the use of money

In contrast to Neurath, Karl Kautsky argued that money would have to be utilized in a socialist economy. Kautsky states the fundamental difference between socialism and capitalism is not the absence of money in the former; rather, the important difference is in the ability for money to become capital under capitalism. In a socialist economy, there would be no incentive to use money as financial capital, therefore money would have a slightly different role in socialism.

Labor-time calculation

Jan Appel drafted a contribution to the Socialist calculation debate which then went through a discussion process before being published as Foundations of Communist Production and Distribution by the General Workers' Union of Germany in 1930. An English translation by Mike Baker was published in 1990.

Interwar debate

Economic calculation problem

Ludwig von Mises believed that private ownership of the means of production was essential for a functional economy, arguing:
Every step that takes us away from private ownership of the means of production and from the use of money also takes us away from rational economics.
His argument against socialism was in response to Otto Neurath arguing for the feasibility of central planning. Mises argued that money and market-determined prices for the means of production were essential in order to make rational decisions regarding their allocation and use.

Criticism of the calculation problem

Bryan Caplan, an anarcho-capitalist economist, has criticized the version of the calculation problem advanced by Mises arguing that the lack of economic calculation makes socialism impossible and not merely inefficient. Caplan argues that socialism makes economic calculation impossible, yet that problem may not be severe enough to make socialism impossible "beyond the realm of possibility". For instance, he points out that the fall of the Soviet Union does not prove that calculation was the main issue there. He suggests that more likely the problems resulted from bad incentives arising out of the one-party political system and degree of power granted to the party-elite.

Knowledge problem

If a universal mind existed, of the kind that projected itself into the scientific fancy of Laplace – a mind that could register simultaneously all the processes of nature and society, that could measure the dynamics of their motion, that could forecast the results of their inter-reactions – such a mind, of course, could a priori draw up a faultless and exhaustive economic plan, beginning with the number of acres of wheat down to the last button for a vest. The bureaucracy often imagines that just such a mind is at its disposal; that is why it so easily frees itself from the control of the market and of Soviet democracy. But, in reality, the bureaucracy errs frightfully in its estimate of its spiritual resources. [...] The innumerable living participants in the economy, state and private, collective and individual, must serve notice of their needs and of their relative strength not only through the statistical determinations of plan commissions but by the direct pressure of supply and demand.
— Leon Trotsky, The Soviet Economy in Danger
Proponents of decentralized economic planning have also criticized central economic planning. For example, Leon Trotsky believed that central planners, regardless of their intellectual capacity, operated without the input and participation of the millions of people who participate in the economy and so they would be unable to respond to local conditions quickly enough to effectively coordinate all economic activity.

Lange model

Oskar Lange responded to Mises' assertion that socialism and social ownership of the means of production implied that rational calculation was impossible by outlining a model of socialism based on neoclassical economics. Lange conceded that calculations would have to be done in value terms rather than using purely natural or engineering criteria, but he asserted that these values could be attained without capital markets and private ownership of the means of production. In Lange's view, this model qualified as socialist because the means of production would be publicly owned with returns to the public enterprises accruing to society as a whole in a social dividend while worker's self-management could be introduced in the public enterprises.

This model came to be referred to as the Lange model. In this model, a Central Planning Board (CPB) would be responsible for setting prices through a trial-and-error approach to establish equilibrium prices, effectively running a Walrasian auction. Managers of the state-owned firms would be instructed to set prices to equal marginal cost (P=MC) so that economic equilibrium and Pareto efficiency would be achieved. The Lange model was expanded upon by Abba Lerner and became known as the Lange–Lerner theorem.

Paul Auerbach and Dimitris Sotiropoulos have criticized the Lange model for degrading the definition of socialism to a form of "capitalism without capital markets" attempting to replicate capitalism's efficiency achievements through economic planning. Auerbach and Sotiropoulos argue that Friedrich Hayek provided an analysis of the dynamics of capitalism that is more consistent with Marxian analysis because Hayek viewed finance as a fundamental aspect of capitalism and any move through collective ownership or policy reform to undermine the role of capital markets would threaten the integrity of the capitalist system. According to Auerbach and Sotiropoulos, Hayek gives an unexpected endorsement to socialism that is more sophisticated than Lange's superficial defense of socialism.

Contemporary contributions

Networked digital feedback

Peter Joseph argues for a transition from fragmented economic data relay to fully integrated, sensor-based digital systems. Using an internet of sensory instruments to measure, track and feed back information, this can unify numerous disparate elements and systems, greatly advancing awareness and efficiency potentials.

In an economic context, this approach could relay and connect data regarding how best to manage resources, production processes, distribution, consumption, recycling, waste disposal behavior, consumer demand and so on. Such a process of networked economic feedback would work on the same principle as modern systems of inventory and distribution found in major commercial warehouses. Many companies today use a range of sensors and sophisticated tracking means to understand rates of demands, exactly what they have, where it is or where it may be moving and when it is gone. It is ultimately an issue of detail and scalability to extend this kind of awareness to all sectors of the economy, macro and micro.

Not only is price no longer needed to gain critical economic feedback, but the information price communicates is long delayed and incomplete in terms of economic measures required to dramatically increase efficiency. Mechanisms related networked digital feedback systems make it possible to efficiently monitor shifting consumer preference, demand, supply and labor value, virtually in real time. Moreover, it can also be used to observe other technical processes price cannot, such as shifts in production protocols, allocation, recycling means, and so on. As of February 2018, it is now possible to track trillions of economic interactions related to the supply chain and consumer behavior by way of sensors and digital relay as seen with the advent of Amazon Go.

Cybernetic coordination

Paul Cockshott, Allin Cottrell, and Andy Pollack have proposed new forms of coordination based on modern information technology for non-market socialism. They argue that economic planning in terms of physical units without any reference to money or prices is computationally tractable given the high-performance computers available for particle physics and weather forecasting. Cybernetic planning would involve an a priori simulation of the equilibration process that idealized markets are intended to achieve.

Participatory economics

Proposals for decentralized economic planning emerged in the late 20th century in the form of participatory economics and negotiated coordination.

Decentralized pricing without markets

David McMullen argues that social ownership of the means of production and the absence of markets for them is fully compatible with a decentralized price system. In a post-capitalist society, transactions between enterprises would entail transfers of social property between custodians rather than an exchange of ownership. Individuals would be motivated by the satisfaction from work and the desire to contribute to good economic outcomes rather than material reward. Bids and offer prices would aim to minimize costs and ensure that output is guided by expected final demand for private and collective consumption. Enterprises and startups would receive their investment funding from project assessment agencies. The required change in human behavior would take a number generations and would have to overcome considerable resistance. However, McMullen believes that economic and cultural development increasingly favors the transition.

Market socialism

James Yunker argues that public ownership of the means of production can be achieved the same way private ownership is achieved in modern capitalism through the shareholder system that separates management from ownership. Yunker posits that social ownership can be achieved by having a public body, designated the Bureau of Public Ownership (BPO), owning the shares of publicly listed firms without affecting market-based allocation of capital inputs. Yunker termed this model pragmatic market socialism and argued that it would be at least as efficient as modern-day capitalism while providing superior social outcomes as public ownership of large and established enterprises would enable profits to be distributed among the entire population rather than going largely to a class of inheriting rentiers.

Mechanism design

Beginning in the 1970s, new insights into the socialist calculation debate emerged from mechanism design theory. According to mechanism design theorists, the debate between Hayek and Lange became a stalemate that lasted for forty years because neither side was speaking the same language as the other, partially because the appropriate language for discussing socialist calculation had not yet been invented. According to these theorists, what was needed was a better understanding of the informational problems that prevent coordination between people. By fusing game theory with information economics, mechanism design provided the language and framework in which both socialists and advocates of capitalism could compare the merits of their arguments. As Palda (2013) writes in his summary of the contributions of mechanism design to the socialist calculation debate, "[i]t seemed that socialism and capitalism were good at different things. Socialism suffered from cheating, or 'moral hazard', more than capitalism because it did not allow company managers to own shares in their own companies. [...] The flip side of the cheating problem in socialism is the lying or 'adverse selection' problem in capitalism. If potential firm managers are either good or bad, but telling them apart is difficult, bad prospects will lie to become a part of the firm".

Relation to neoclassical economics

In his book Whither Socialism?, Joseph Stiglitz criticized models of market socialism from the era of the socialist calculation debate in the 1930s as part of a more general criticism of neoclassical general equilibrium theory, proposing that market models be augmented with insights from information economics. Alec Nove and Janos Kornai held similar positions regarding economic equilibrium. Both Nove and Kornai argued that because perfect equilibrium does not exist, a comprehensive economic plan for production cannot be formulated, making planning ineffective just as real-world market economies do not conform to the hypothetical state of perfect competition. In his book The Economics of Feasible Socialism, Nove also outlined a solution involving a socialist economy consisting of a mixture of macro-economic planning with market-based coordination for enterprises where large industries would be publicly owned and small- to medium-sized concerns would be organized as cooperatively owned enterprises.

Post-capitalism

From Wikipedia, the free encyclopedia
Post-capitalism is a state in which the economic systems of the world can no longer be described as forms of capitalism. Various individuals and political ideologies have speculated on what would define such a world. According to some classical Marxist and some social evolutionary theories, post-capitalist societies may come about as a result of spontaneous evolution as capitalism becomes obsolete. Others propose models to intentionally replace capitalism. The most notable among them are socialism and anarchism.

In 1993, Peter Drucker outlined a possible evolution of capitalistic society in his book Post-Capitalist Society. The book stated that knowledge, rather than capital, land, or labor, is the new basis of wealth. The classes of a fully post-capitalist society are expected to be divided into knowledge workers or service workers, in contrast to the capitalists and proletarians of a capitalist society. In the book, Drucker estimated the transformation to post-capitalism would be completed in 2010–2020.

Drucker also argued for rethinking the concept of intellectual property by creating a universal licensing system. Consumers would subscribe for a cost and producers would assume that everything is reproduced and freely distributed through social networks.

In 2015, according to Paul Mason the rise of income inequality, repeating cycles of boom and bust and capitalism’s contributions to climate change has led economists, political thinkers and philosophers to begin to seriously consider how a post-capitalistic society would look and function. Post-capitalism is expected to be made possible with further advances in automation and information technology – both of which are effectively causing production costs to trend towards zero.

Nick Srnicek and Alex Williams identify a crisis in capitalism's ability and willingness to employ all members of society, arguing that "there is a growing population of people that are situated outside formal, waged work, making do with minimal welfare benefits, informal subsistence work, or by illegal means."

Anarchism

Heritage check system

Heritage check system, a socioeconomic plan that retains a market economy, but removes fractional reserve lending power from banks and limits government printing of money to offset deflation with money printed being used to buy materials to back the currency, pay for government programs in lieu of taxes, with the remainder to be split evenly among all citizens to stimulate the economy (termed a "heritage check" for which the system is named). As presented by the original author of the idea, Robert Heinlein, in his book For Us, The Living: A Comedy of Customs, the system would be self-reinforcing and eventually result in a regular heritage checks able to provide a modest living for most citizens.

Economic democracy

Participatory economy

In his book Of the People, By the People: The Case for a Participatory Economy, Robin Hahnel describes a post-capitalist economy called the participatory economy. The book ends with the proposal of the Green New Deal, a package of policies that address climate change and financial crises.

The participatory economy focuses on the participation of all citizens through the creation of worker councils and consumer councils. Hahnel emphasizes the direct participation of worker and consumers rather than appointing representatives. The councils are concerned with large-scale issues of production and consumption and are broken into various bodies tasked with researching future development projects.

In a participatory economy, economic rewards would be offered according to need, the amount of which would be determined democratically by the workers council. Hahnel also calls for "economic justice" by rewarding people for their effort and diligence rather than accomplishments or prior ownership. A worker’s effort is to be determined by their co-workers. Consumption rights are then rewarded according to the effort ratings. The worker has the choice to decide what they consume using their consumption rights. Hahnel does not address the idea of money, currency, or how consumption rights would be tracked.

Planning in a participatory economy is done through the councils. The process is horizontal across the committees as opposed to vertical. All council members, the workers and consumers, participate directly in planning unlike in Soviet-type economies and other democratic planning proposals in which planning is done by representatives. Planning is an iterative procedure, always being changed and improved upon, that is accomplished at the level of either work or consumption. All information and proposals are freely available to everyone, those inside and outside of the council, so that the social cost of each proposal can be determined and voted on. Long-term plans such as structuring public transportation, residential zones and recreational areas, are to be proposed by delegates and approved by direct democracy (i.e. voting by the population).

Hahnel argues that a participatory economy will return empathy to our purchasing choices. Capitalism removes the knowledge of how and by whom a product was made: "When we eat a salad the market systematically deletes information about the migrant workers who picked it". By removing the human element from goods, consumers only consider their own satisfaction and need when consuming products. Introducing worker and consumer councils would reintroduce the knowledge of where, how and by whom products were manufactured. A participatory economy is expected to also introduce more socially oriented goods, such as parks, clean air, and public health care, through the interaction of the two councils.

For those that call the participatory economy utopian, Albert and Hahnel counter:
Are we being utopian? It is utopian to expect more from a system than it can possibly deliver. To expect equality and justice—or even rationality—from capitalism is utopian. To expect social solidarity from markets, or self-management from central planning, is equally utopian. To argue that competition can yield empathy or that authoritarianism can promote initiative or that keeping most people from decision making can employ human potential most fully: these are utopian fantasies without question. But to recognize human potentials and to seek to embody their development into a set of economic institutions and then to expect those institutions to encourage desirable outcomes is no more than reasonable theorizing. What is utopian is not planting new seeds but expecting flowers from dying weeds.

Socialism

Socialism often implies common ownership of companies and a planned economy, though as an inherently pluralistic ideology, it is argued whether either are essential features. In his book PostCapitalism: A Guide to our Future, Paul Mason argues that centralized planning, even with the advanced technology of today, is unachievable. Rejecting central planning as both technically unachievable and undesirable, Michael Albert and Robin Hahnel argue that democratic planning provides a viable basis for creating a participatory economy

Technology as a driver of post-capitalism

Much of the speculation surrounding the proposed fate of the capitalist system stems from predictions about the future integration of technology into economics. The evolution and increasing sophistication of both automation and information technology is said to threaten jobs and highlight internal contradictions in Capitalism which will allegedly ultimately lead to its collapse.

Automation

Technological change which has driven unemployment has historically been as a result of ‘mechanical-muscle’ machines which have reduced the need for human labour. Just as horses were once employed but were gradually made obsolete by the invention of the automobile, humans' jobs have also been affected throughout history. A modern example of this technological unemployment is the replacement of retail cashiers by self-service checkouts. The invention and development of ‘mechanical-mind’ processes or “brain labour” is thought to threaten jobs at an unprecedented scale, with Oxford Professors Carl Benedikt Frey and Michael Osborne estimating that 47 percent of US jobs are at risk of automation. If this leads to a world where human labour is no longer needed then our current market system models, which rely on scarcity, may have to adapt or fail. It is argued that this has been a factor in the creation of many of what David Graeber calls 'bullshit jobs', where, in large bureaucracies, production of anything is not the goal, but exist solely for reasons such as providing sociological benefit to the manager employing them.

Information technology

Postcapitalism is said to be possible due to major changes information technology has brought about in recent years. It has blurred the edges between work and free time  and loosened the relationship between work and wages. Significantly, information is corroding the market’s ability to form prices correctly. Information is abundant and information goods are freely replicable. Goods such as music, software or databases do have a production cost, but once made can be copied/pasted infinitely. If the normal price mechanism of capitalism prevails, then the price of any good which has essentially no cost of reproduction will fall towards zero. This lack of scarcity is a problem for our models, which try to counter by developing monopolies in the form of giant tech companies to keep information scarce and commercial. But many significant commodities in the digital economy are now free and open-source, such as Linux, Firefox, and Wikipedia.

Anti-capitalism

From Wikipedia, the free encyclopedia


Anti-capitalism is a political ideology and movement encompassing a variety of attitudes and ideas that oppose capitalism. In this sense, anti-capitalists are those who wish to replace capitalism with another type of economic system, usually some form of socialism.

Socialism

Karl Marx, considered by many as one of the founding fathers of anti-capitalist thought

Socialism advocates public or direct worker ownership and administration of the means of production and allocation of resources, and a society characterized by equal access to resources for all individuals, with an egalitarian method of compensation.
  1. A theory or policy of social organisation which aims at or advocates the ownership and democratic control of the means of production, by workers or the community as a whole, and their administration or distribution in the interests of all.
  2. Socialists argue for a cooperative/community economy, or the commanding heights of the economy, with democratic control by the people over the state, although there have been some undemocratic philosophies. "State" or "worker cooperative" ownership is in fundamental opposition to "private" ownership of means of production, which is a defining feature of capitalism. Most socialists argue that capitalism unfairly concentrates power, wealth and profit, among a small segment of society that controls capital and derives its wealth through exploitation.
Socialists argue that the accumulation of capital generates waste through externalizations that require costly corrective regulatory measures. They also point out that this process generates wasteful industries and practices that exist only to generate sufficient demand for products to be sold at a profit (such as high-pressure advertisement); thereby creating rather than satisfying economic demand.

Socialists argue that capitalism consists of irrational activity, such as the purchasing of commodities only to sell at a later time when their price appreciates, rather than for consumption, even if the commodity cannot be sold at a profit to individuals in need; they argue that making money, or accumulation of capital, does not correspond to the satisfaction of demand.

Private ownership imposes constraints on planning, leading to inaccessible economic decisions that result in immoral production, unemployment and a tremendous waste of material resources during crisis of overproduction. According to socialists, private property in the means of production becomes obsolete when it concentrates into centralized, socialized institutions based on private appropriation of revenue (but based on cooperative work and internal planning in allocation of inputs) until the role of the capitalist becomes redundant. With no need for capital accumulation and a class of owners, private property in the means of production is perceived as being an outdated form of economic organization that should be replaced by a free association of individuals based on public or common ownership of these socialized assets. Socialists view private property relations as limiting the potential of productive forces in the economy.

Early socialists (Utopian socialists and Ricardian socialists) criticized capitalism for concentrating power and wealth within a small segment of society, and does not utilise available technology and resources to their maximum potential in the interests of the public.

Anarchism and libertarian socialism

Emma Goldman famously denounced wage slavery by saying: "The only difference is that you are hired slaves instead of block slaves."
 
For the influential German individualist anarchist philosopher Max Stirner, "private property is a spook which "lives by the grace of law" and it "becomes 'mine' only by effect of the law". In other words, private property exists purely "through the protection of the State, through the State's grace." Recognising its need for state protection, Stirner argued that "[i]t need not make any difference to the 'good citizens' who protects them and their principles, whether an absolute King or a constitutional one, a republic, if only they are protected. And what is their principle, whose protector they always 'love'? Not that of labour", rather it is "interest-bearing possession ... labouring capital, therefore ... labour certainly, yet little or none at all of one's own, but labour of capital and of the—subject labourers"." French anarchist Pierre Joseph Proudhon opposed government privilege that protects capitalist, banking and land interests, and the accumulation or acquisition of property (and any form of coercion that led to it) which he believed hampers competition and keeps wealth in the hands of the few. The Spanish individualist anarchist Miguel Gimenez Igualada saw "capitalism [as] an effect of government; the disappearance of government means capitalism falls from its pedestal vertiginously...That which we call capitalism is not something else but a product of the State, within which the only thing that is being pushed forward is profit, good or badly acquired. And so to fight against capitalism is a pointless task, since be it State capitalism or Enterprise capitalism, as long as Government exists, exploiting capital will exist. The fight, but of consciousness, is against the State.".

Within anarchism there emerged a critique of wage slavery which refers to a situation perceived as quasi-voluntary slavery, where a person's livelihood depends on wages, especially when the dependence is total and immediate. It is a negatively connoted term used to draw an analogy between slavery and wage labor by focusing on similarities between owning and renting a person. The term wage slavery has been used to criticize economic exploitation and social stratification, with the former seen primarily as unequal bargaining power between labor and capital (particularly when workers are paid comparatively low wages, e.g. in sweatshops), and the latter as a lack of workers' self-management, fulfilling job choices and leisure in an economy. Libertarian socialists believe if freedom is valued, then society must work towards a system in which individuals have the power to decide economic issues along with political issues. Libertarian socialists seek to replace unjustified authority with direct democracy, voluntary federation, and popular autonomy in all aspects of life, including physical communities and economic enterprises. With the advent of the industrial revolution, thinkers such as Proudhon and Marx elaborated the comparison between wage labor and slavery in the context of a critique of societal property not intended for active personal use, Luddites emphasized the dehumanization brought about by machines while later Emma Goldman famously denounced wage slavery by saying: "The only difference is that you are hired slaves instead of block slaves.". American anarchist Emma Goldman believed that the economic system of capitalism was incompatible with human liberty. "The only demand that property recognizes," she wrote in Anarchism and Other Essays, "is its own gluttonous appetite for greater wealth, because wealth means power; the power to subdue, to crush, to exploit, the power to enslave, to outrage, to degrade." She also argued that capitalism dehumanized workers, "turning the producer into a mere particle of a machine, with less will and decision than his master of steel and iron."

Noam Chomsky contends that there is little moral difference between chattel slavery and renting one's self to an owner or "wage slavery". He feels that it is an attack on personal integrity that undermines individual freedom. He holds that workers should own and control their workplace. Many libertarian socialists argue that large-scale voluntary associations should manage industrial manufacture, while workers retain rights to the individual products of their labor. As such, they see a distinction between the concepts of "private property" and "personal possession". Whereas "private property" grants an individual exclusive control over a thing whether it is in use or not, and regardless of its productive capacity, "possession" grants no rights to things that are not in use.

In addition to individualist anarchist Benjamin Tucker's "big four" monopolies (land, money, tariffs, and patents), Kevin Carson argues that the state has also transferred wealth to the wealthy by subsidizing organizational centralization, in the form of transportation and communication subsidies. He believes that Tucker overlooked this issue due to Tucker's focus on individual market transactions, whereas Carson also focuses on organizational issues. Carson holds that “capitalism, arising as a new class society directly from the old class society of the Middle Ages, was founded on an act of robbery as massive as the earlier feudal conquest of the land. It has been sustained to the present by continual state intervention to protect its system of privilege without which its survival is unimaginable.” Carson coined the pejorative term "vulgar libertarianism," a phrase that describes the use of a free market rhetoric in defense of corporate capitalism and economic inequality. According to Carson, the term is derived from the phrase "vulgar political economy," which Karl Marx described as an economic order that "deliberately becomes increasingly apologetic and makes strenuous attempts to talk out of existence the ideas which contain the contradictions [existing in economic life]."

Marxism

Capital: Critique of Political Economy, by Karl Marx, is a critical analysis of political economy, meant to reveal the economic laws of the capitalist mode of production
If we have chosen the position in life in which we can most of all work for mankind, no burdens can bow us down, because they are sacrifices for the benefit of all; then we shall experience no petty, limited, selfish joy, but our happiness will belong to millions, our deeds will live on quietly but perpetually at work, and over our ashes will be shed the hot tears of noble people.
— Karl Marx, 1837
Karl Marx saw capitalism as a historical stage, once progressive but which would eventually stagnate due to internal contradictions and would eventually be followed by socialism. Marx claimed that capitalism was nothing more than a necessary stepping stone for the progression of man, which would then face a political revolution before embracing the classless society. Marxists define capital as "a social, economic relation" between people (rather than between people and things). In this sense they seek to abolish capital. They believe that private ownership of the means of production enriches capitalists (owners of capital) at the expense of workers ("the rich get richer, and the poor get poorer"). In brief, they argue that the owners of the means of production do not work and therefore exploit the workerforce. In Karl Marx's view, the capitalists would eventually accumulate more and more capital impoverishing the working class, creating the social conditions for a revolution that would overthrow the institutions of capitalism. Private ownership over the means of production and distribution is seen as a dependency of non-owning classes on the ruling class, and ultimately a source of restriction of human freedom.

Barter

Barter is a system of exchange where goods or services are directly exchanged for other goods or services without using a medium of exchange, such as money. It is distinguishable from gift economies in many ways; one of them is that the reciprocal exchange is immediate and not delayed in time. It is usually bilateral, but may be multilateral (i.e., mediated through barter organizations) and, in most developed countries, usually only exists parallel to monetary systems to a very limited extent. Barter, as a replacement for money as the method of exchange, is used in times of monetary crisis, such as when the currency may be either unstable (e.g., hyperinflation or deflationary spiral) or simply unavailable for conducting commerce. Bartering could be considered a social starting point towards an anti-capitalist system, by negating the need for a medium of exchange.

Wage slavery

Wage slavery refers to a situation where a person's livelihood depends on wages or a salary, especially when the dependence is total and immediate. It is a pejorative term used to draw an analogy between slavery and wage labor by focusing on similarities between owning and renting a person.

The term wage slavery has been used to criticize exploitation of labour and social stratification, with the former seen primarily as unequal bargaining power between labor and capital (particularly when workers are paid comparatively low wages, e.g. in sweatshops), and the latter as a lack of workers' self-management, fulfilling job choices, and leisure in an economy. The criticism of social stratification covers a wider range of employment choices bound by the pressures of a hierarchical society to perform otherwise unfulfilling work that deprives humans of their "species character" not only under threat of starvation or poverty, but also of social stigma and status diminution. It has been argued by some centre-left and left leaning activists that the economy of the contemporary United States constitutes a softer form of wage slavery, in which conditions are not grinding, but nonetheless not conducive to individual economic progress.

In cryptography, a public key certificate, also known as a digital certificate or identity certificate, is an electronic document used to prove the ownership of a public key. The certificate includes information about the key, information about the identity of its owner (called the subject), and the digital signature of an entity that has verified the certificate's contents (called the issuer). If the signature is valid, and the software examining the certificate trusts the issuer, then it can use that key to communicate securely with the certificate's subject. In email encryption, code signing, and e-signature systems, a certificate's subject is typically a person or organization. However, in Transport Layer Security (TLS) a certificate's subject is typically a computer or other device, though TLS certificates may identify organizations or individuals in addition to their core role in identifying devices. TLS, sometimes called by its older name Secure Sockets Layer (SSL), is notable for being a part of HTTPS, a protocol for securely browsing the web.

In a typical public-key infrastructure (PKI) scheme, the certificate issuer is a certificate authority (CA), usually a company that charges customers to issue certificates for them. By contrast, in a web of trust scheme, individuals sign each other's keys directly, in a format that performs a similar function to a public key certificate.

The most common format for public key certificates is defined by X.509. Because X.509 is very general, the format is further constrained by profiles defined for certain use cases, such as Public Key Infrastructure (X.509) as defined in RFC 5280.

Types of certificate

The roles of root certificate, intermediate certificate and end-entity certificate as in the chain of trust.

TLS/SSL server certificate

In TLS (an updated replacement for SSL), a server is required to present a certificate as part of the initial connection setup. A client connecting to that server will perform the certification path validation algorithm:
  1. The subject of the certificate matches the hostname (i.e. domain name) to which the client is trying to connect;
  2. The certificate is signed by a trusted certificate authority.
The primary hostname (domain name of the website) is listed as the Common Name in the Subject field of the certificate. A certificate may be valid for multiple hostnames (multiple websites). Such certificates are commonly called Subject Alternative Name (SAN) certificates or Unified Communications Certificates (UCC). These certificates contain the field Subject Alternative Name, though many CAs will also put them into the Subject Common Name field for backward compatibility. If some of the hostnames contain an asterisk (*), a certificate may also be called a wildcard certificate.

A TLS server may be configured with a self-signed certificate. When that is the case, clients will generally be unable to verify the certificate, and will terminate the connection unless certificate checking is disabled.

As per the applications, SSL Certificates can be classified into three types:
  • Domain Validation SSL;
  • Organization Validation SSL;
  • Extended Validation SSL.

TLS/SSL client certificate

Client certificates are less common than server certificates, and are used to authenticate the client connecting to a TLS service, for instance to provide access control. Because most services provide access to individuals, rather than devices, most client certificates contain an email address or personal name rather than a hostname. Also, because authentication is usually managed by the service provider, client certificates are not usually issued by a public CA that provides server certificates. Instead, the operator of a service that requires client certificates will usually operate their own internal CA to issue them. Client certificates are supported by many web browsers, but most services use passwords and cookies to authenticate users, instead of client certificates.

Client certificates are more common in RPC systems, where they are used to authenticate devices to ensure that only authorized devices can make certain RPC calls.

Email certificate

In the S/MIME protocol for secure email, senders need to discover which public key to use for any given recipient. They get this information from an email certificate. Some publicly trusted certificate authorities provide email certificates, but more commonly S/MIME is used when communicating within a given organization, and that organization runs its own CA, which is trusted by participants in that email system.

EMV certificate

EMV payment cards are preloaded with EMV Certificate, Card Issuer Certificate, signed by EMV Certificate Authority to validate authenticity of the payment card during the payment transaction. EMV CA Certificate public key is loaded on ATM or POS and used for validating Card Issuer Certificate.

Code signing certificate

Certificates can also be used to validate signatures on programs to ensure they were not tampered with during delivery.

Qualified certificate

A certificate identifying an individual, typically for electronic signature purposes. These are most commonly used in Europe, where the eIDAS regulation standardizes them and requires their recognition.

Root certificate

A self-signed certificate used to sign other certificates. Also sometimes called a trust anchor.

Intermediate certificate

A certificate used to sign other certificates. An intermediate certificate must be signed by another intermediate certificate, or a root certificate.

End-entity or leaf certificate

Any certificate that cannot be used to sign other certificates. For instance, TLS/SSL server and client certificates, email certificates, code signing certificates, and qualified certificates are all end-entity certificates.

Self-signed certificate

A certificate with a subject that matches its issuer, and a signature that can be verified by its own public key. Most types of certificate can be self-signed. Self-signed certificates are also often called snake oil certificates to emphasize their untrustworthiness.

Common fields

These are some of the most common fields in certificates. Most certificates contain a number of fields not listed here. Note that in terms of a certificate's X.509 representation, a certificate is not "flat" but contains these fields nested in various structures within the certificate.
  • Serial Number: Used to uniquely identify the certificate within a CA's systems. In particular this is used to track revocation information.
  • Subject: The entity a certificate belongs to: a machine, an individual, or an organization.
  • Issuer: The entity that verified the information and signed the certificate.
  • Not Before: The earliest time and date on which the certificate is valid. Usually set to a few hours or days prior to the moment the certificate was issued, to avoid clock skew problems.
  • Not After: The time and date past which the certificate is no longer valid.
  • Key Usage: The valid cryptographic uses of the certificate's public key. Common values include digital signature validation, key encipherment, and certificate signing.
  • Extended Key Usage: The applications in which the certificate may be used. Common values include TLS server authentication, email protection, and code signing.
  • Public Key: A public key belonging to the certificate subject.
  • Signature Algorithm: The algorithm used to sign the public key certificate.
  • Signature: A signature of the certificate body by the issuer's private key.

Sample certificate

This is an example of a decoded SSL/TLS certificate retrieved from SSL.com's website. The issuer's common name (CN) is shown as SSL.com EV SSL Intermediate CA RSA R3, identifying this as an Extended Validation (EV) certificate. Validated information about the website's owner (SSL Corp) is located in the Subject field. The X509v3 Subject Alternative Name field contains a list of domain names covered by the certificate. The X509v3 Extended Key Usage and X509v3 Key Usage fields show all appropriate uses.

Usage in the European Union

In the European Union, electronic signatures on legal documents are commonly performed using digital signatures with accompanying identity certificates. This is largely because such signatures are granted the same enforceability as handwritten signatures under eIDAS, an EU regulation.

Certificate authorities

The procedure of obtaining a Public key certificate

In the X.509 trust model, a certificate authority (CA) is responsible for signing certificates. These certificates act as an introduction between two parties, which means that a CA acts as a trusted third party. A CA processes requests from people or organizations requesting certificates (called subscribers), verifies the information, and potentially signs an end-entity certificate based on that information. To perform this role effectively, a CA needs to have one or more broadly trusted root certificates or intermediate certificates and the corresponding private keys. CAs may achieve this broad trust by having their root certificates included in popular software, or by obtaining a cross-signature from another CA delegating trust. Other CAs are trusted within a relatively small community, like a business, and are distributed by other mechanisms like Windows Group Policy.

Certificate authorities are also responsible for maintaining up-to-date revocation information about certificates they have issued, indicating whether certificates are still valid. They provide this information through Online Certificate Status Protocol (OCSP) and/or Certificate Revocation Lists (CRLs). Some of the larger certificate authorities in the market include IdenTrust, DigiCert, and Sectigo.

Root programs

Some major software contain a list of certificate authorities that are trusted by default. This makes it easier for end-users to validate certificates, and easier for people or organizations that request certificates to know which certificate authorities can issue a certificate that will be broadly trusted. This is particularly important in HTTPS, where a web site operator generally wants to get a certificate that is trusted by nearly all potential visitors to their web site.

The policies and processes a provider uses to decide which certificate authorities their software should trust are called root programs. The most influential root programs are:
Browsers other than Firefox generally use the operating system's facilities to decide which certificate authorities are trusted. So, for instance, Chrome on Windows trusts the certificate authorities included in the Microsoft Root Program, while on macOS or iOS, Chrome trusts the certificate authorities in the Apple Root Program. Edge and Safari use their respective operating system trust stores as well, but each is only available on a single OS. Firefox uses the Mozilla Root Program trust store on all platforms.

The Mozilla Root Program is operated publicly, and its certificate list is part of the open source Firefox web browser, so it is broadly used outside Firefox. For instance, while there is no common Linux Root Program, many Linux distributions, like Debian, include a package that periodically copies the contents of the Firefox trust list, which is then used by applications.

Root programs generally provide a set of valid purposes with the certificates they include. For instance, some CAs may be considered trusted for issuing TLS server certificates, but not for code signing certificates. This is indicated with a set of trust bits in a root certificate storage system.

Certificates and website security

The most common use of certificates is for HTTPS-based web sites. A web browser validates that an HTTPS web server is authentic, so that the user can feel secure that his/her interaction with the web site has no eavesdroppers and that the web site is who it claims to be. This security is important for electronic commerce. In practice, a web site operator obtains a certificate by applying to a certificate authority with a certificate signing request. The certificate request is an electronic document that contains the web site name, company information and the public key. The certificate provider signs the request, thus producing a public certificate. During web browsing, this public certificate is served to any web browser that connects to the web site and proves to the web browser that the provider believes it has issued a certificate to the owner of the web site.

As an example, when a user connects to https://www.example.com/ with their browser, if the browser does not give any certificate warning message, then the user can be theoretically sure that interacting with https://www.example.com/ is equivalent to interacting with the entity in contact with the email address listed in the public registrar under "example.com", even though that email address may not be displayed anywhere on the web site. No other surety of any kind is implied. Further, the relationship between the purchaser of the certificate, the operator of the web site, and the generator of the web site content may be tenuous and is not guaranteed. At best, the certificate guarantees uniqueness of the web site, provided that the web site itself has not been compromised (hacked) or the certificate issuing process subverted.

A certificate provider can opt to issue three types of certificates, each requiring its own degree of vetting rigor. In order of increasing rigor (and naturally, cost) they are: Domain Validation, Organization Validation and Extended Validation. These rigors are loosely agreed upon by voluntary participants in the CA/Browser Forum.

Validation levels

Domain validation

A certificate provider will issue a Domain Validation (DV) class certificate to a purchaser if the purchaser can demonstrate one vetting criterion: the right to administratively manage a domain name.

Organization validation

A certificate provider will issue an Organization Validation (OV) class certificate to a purchaser if the purchaser can meet two criteria: the right to administratively manage the domain name in question, and perhaps, the organization's actual existence as a legal entity. A certificate provider publishes its OV vetting criteria through its Certificate Policy.

Extended validation

To acquire an Extended Validation (EV) certificate, the purchaser must persuade the certificate provider of its legal identity, including manual verification checks by a human. As with OV certificates, a certificate provider publishes its EV vetting criteria through its Certificate Policy.

Browsers will generally offer users a visual indication of the legal identity when a site presents an EV certificate. Most browsers show the legal name before the domain, and use a bright green color to highlight the change. In this way, the user can see the legal identity of the owner has been verified.

Weaknesses

A web browser will give no warning to the user if a web site suddenly presents a different certificate, even if that certificate has a lower number of key bits, even if it has a different provider, and even if the previous certificate had an expiry date far into the future. However a change from an EV certificate to a non-EV certificate will be apparent as the green bar will no longer be displayed. Where certificate providers are under the jurisdiction of governments, those governments may have the freedom to order the provider to generate any certificate, such as for the purposes of law enforcement. Subsidiary wholesale certificate providers also have the freedom to generate any certificate.

All web browsers come with an extensive built-in list of trusted root certificates, many of which are controlled by organizations that may be unfamiliar to the user. Each of these organizations is free to issue any certificate for any web site and have the guarantee that web browsers that include its root certificates will accept it as genuine. In this instance, end users must rely on the developer of the browser software to manage its built-in list of certificates and on the certificate providers to behave correctly and to inform the browser developer of problematic certificates. While uncommon, there have been incidents in which fraudulent certificates have been issued: in some cases, the browsers have detected the fraud; in others, some time passed before browser developers removed these certificates from their software.

The list of built-in certificates is also not limited to those provided by the browser developer: users (and to a degree applications) are free to extend the list for special purposes such as for company intranets. This means that if someone gains access to a machine and can install a new root certificate in the browser, that browser will recognize websites that use the inserted certificate as legitimate.

For provable security, this reliance on something external to the system has the consequence that any public key certification scheme has to rely on some special setup assumption, such as the existence of a certificate authority.

Usefulness versus unsecured web sites

In spite of the limitations described above, certificate-authenticated TLS is considered mandatory by all security guidelines whenever a web site hosts confidential information or performs material transactions. This is because, in practice, in spite of the weaknesses described above, web sites secured by public key certificates are still more secure than unsecured http:// web sites.
