Production is not possible without relations of production – humans cannot produce outside of a social structure, whether a nation or a family – relations of production exist for all producers. The basis of the relations of production is ownership of the means of production. When the means of production become public property, then all people are able to exercise their freedom in relation to the productive forces through the social and political structures of society. To the extent that people enjoy equal rights they are thus able exercise these rights freely in the real development of society, unhindered by the barriers of private property. With the existance of private property, competition and exploitation hinder the real freedom of humans, where only a handful have ownership of the means of production. Throughout history social property appeared in the form of the property of the clan and the tribe (primitive communism), public or state property (socialism), cooperative and community property (communism), etc. – while private ownership appears in history through: slave property, feudal property, and capitalist property. From all forms of ownership correspond lesser or greater types of exploitation of human by human.
