 While socially utilised means of production are under public control, personal belongings or property of a personal nature that does not involve mass production of goods remains unaffected by the state.Because Marxism–Leninism has historically been the state ideology of countries who were economically undeveloped prior to socialist revolution, or whose economies were nearly obliterated by war such as the German Democratic Republic, the primary goal before achieving communism was the development of socialism in itself.Such was the case in the Soviet Union, where the economy was largely agrarian and urban industry was in a primitive stage.
