According to the Encyclopedia Britannica, the public collectively owns, at a minimum, the major means of production in an ideal communist state. Public ownership and control extend to natural resources as well. In communism, there is no private property or profit-driven economy.
The International Encyclopedia of the Social Sciences notes that communism has seen various types of applications and that the character of communist states has diverged significantly from the theoretical character of a communist state in Karl Marx's Communist Manifesto. For example, where Marx saw the urban proletariat as the force that would bring about the communist transformation, Mao Zedong saw the rural peasantry as the essential driving force of the revolution.
