Common to all factions of socialism was the criticism of capitalism as unjust (inequality of income distribution) and irrational (business cycle, unemployment) social and economic system. All socialist believed in the need to replace capitalism with more just and more rational system. They differed, however, in their views about the future socialist society and about the mode of transition to it. Marxist perceived socialism as a highly organized centrally controlled society in which private ownership is replaced by public (state) ownership and market by central planning. Some others pictured socialism as a decentralized economy based on employee ownership of firms and modified form of market coordination. Marxists believed, that the transition to socialism would start by a violent revolution. West European socialists advocated a peaceful transition using the democratic political process
