Communism as an ideal type, an economic system under which all property is communally owned and no social distinctions are made on the basis of people’s ability to produce.
Communism is a set of political and economic ideas in which the means of production and distribution are controlled by an authoritarian state with the expressed goal of creating an egalitarian social order. Communism as developed by Lenin and institutionalized throughout Eastern Europe (until 1990) and China bears little resemblance to Marx's vision.
Communism is an economic system under which the government controls the factors of production. Land, labor, and capital are under the control of the government and entrepreneurship is supplied by the government.
As a result, all the economic decisions about production, distribution, consumption, and property ownership are made by the government. It decides what will be produced, who will produce it, how many units will be made, how much it will cost, and who will receive it. Supply and demand and competition have no influence in this system. Central government planners make all the economic decisions about production and resource allocation.
