There have been a number of proposals for a new economic system to replace capitalism. Some are theorized to come about through spontaneous evolutionary processes as capitalism becomes obsolete, while others are proposed models to intentionally replace capitalism. The most notable among them are:
A Steady state economy is an economy where economic growth is stable, combined with stable population growth and patterns of consumption. Economists including Adam Smith and John Maynard Keynes postulated that capitalism would evolve into a steady state economy.
Communism, a hypothetical historical era, based on a mature form of the socialist mode of production according to Leninism but interchangeable with the word socialism according to Marxism, wherein production is not organized on the premise of valorization through exploitation, and distribution follows the principle "to each according to need". Communism would presume the abolition of labour as a separate sphere of life one is coerced into for survival; the material means of subsistence would thus be said to be held in common.
In such a society the dominant form of economic organization and government that controls the economy is a Plutocracy or Plutarchy. The governed subjects may be unaware of the true nature of their system as it may have the trappings of or claim to be a republic or democracy, however the direct or indirect rule is controlled by a very small number who are the very wealthiest.
Plutocracy, an economic system based on private ownership of the means of production, usually meaning a form of Capitalism or other system in which rule is directly or indirectly by the very wealthy, or the power that is provided by immense wealth.
Plutarchy, a form of plutocracy which is also an oligarchy, which is governed by a small group of people.
A form of direct and/or consensus democracy, where all people would be allowed to vote for every major economic matter and thus directly participate in decision-making. Theoretically such a system is plausible on a large scale, especially with the use of modern technology.
Non-trading cooperative society, where private organizations are not "owned" (capitalised) by anyone and are democratically operated. "Profit" made by these organisations can go towards research and development or charity, or increasing the cash asset of the organisation for growth. Private property and working for a wage/salary are not precluded by this system. Share markets would become a thing of the past. Gradual transition to this system is possible through outcompetition with capitalist counterparts due to fund channelling and consumer sentiment.
Distributism, a system encouraging the widest possible distribution of the means of production, so that as many people as possible can be entrepreneurs. Small businesses that support one family are valued more highly than large corporations and large government bureaucracies.
Gift economy, a society where valuable goods and services are regularly given without any explicit agreement for immediate or future rewards.
Post-capitalistic, Post scarcity industrial utopia, a society where exponential increases in productivity and automation have led to a self-sufficient economy. Such an economy no longer requires the intervention of humans in order to meet the needs and desires of the world population. Such an economic system could coexist with any political system capable of assuring the sustainability of the system. Proponents include The Venus Project, which calls its vision "resource-based economy".
Post-capitalistic dystopia, a society where traditional capitalism has collapsed abruptly or just degenerated into dysfunction, but without being superseded properly by any fundamentally different system. Instead such societies are typically characterised by various combinations of elements of feudalism or bastard feudalism, kleptocracy and cryptocracy. Often these systems will pose under the guise of being highly evolved and particularly just and democratic forms of capitalism or communism. In such societies governments have an important role performing as the legitimising front, ensuring the availability of a population of consuming workers under strict micromanagement. A population where the interpersonal relationships are capitalised through tax or toll by obscure corporations controlling the infrastructure, in particular the communications infrastructure.
