The period in which capitalism becomes increasingly insufficient as an economic system and immediately after the proletarian conquest of the state, an economic system that features elements of both socialism and capitalism will probably exist until both the productive forces of the economy and the cultural and social attitudes develop to a point where they satisfy the requirements for a full socialist society (one that has lost the need for monetary value, wage labor and capital accumulation). Specifically, market relations will still exist but economic units are either nationalized or re-organized into cooperatives. This transitional phase is sometimes described as "state capitalism" or "market socialism".
