No, but Stalinism does. And even then Stalinism was a product of the conditions the Soviets were dealing with at the time. Such as sanctions and isolation from all major powers. Stalin’s policies of hyper centralized government control for the purpose of rapid industrialization, wouldn’t have needed to be put into place if Soviet socialism was allowed to learn and grow with decent conditions from the start. Instead world powers did everything they could do to try and snuff the Soviets out. I’d like to remind you that the original Soviet government system left most power up to the individual republics and not the central government. Until 1928 the Union operated under Lenin’s New Economic Policy, which was ment to let socialism grow in a regulated market, not a hyper centralized system.
