But in this way, the society isn't prepared for the socialism, especially the economy basic and the ideology. Most socialism states such as the USSR and the PRC, were founded in that method. It relied on the revolution and can't avoid bleeding and sacrifice. .
Take the USSR for example, the Communist Party obtained their strength and power by the revolutionary path, subverting the political, social, and other orders in the old era. And when the regime was established its consciousness and economic had not been prepared for it. Because the Bolshevik hadn't been formed as a part of the economic and social life before it came to power. They hadn't take root in the life of the nation.
The Bolshevik was based on the proletariat and the poor who didn't own the productive materials. And the proletariat and the poor are "the masses upon which the party or the new bureaucracy must lean and with which its interests are most closely allied" ! This was true at first. But after that, in the name of the proletariat and the poor, the Bolshevik established state-owned and collective ownership. On the way to public ownership the Bolshevik treated the peasants so cruelly that coursed a lot of death.
However, who substantially controlled the productive materials, the working class or the peasants? Neither. They couldn't dominate what they "own", they even could not do they wanted to do. In fact the people didn't have independent property, The representatives of the working class----the bureaucracy were the real master of the nationalized property. This was really a kind of ridicule to public's ownership. Where was the economic democracy?.
Just like Milovan D.Jilas said, he who grabs power grabs privileges and indirectly grabs property . The political power and the ownership were in the same hands, but these hands were not the workers' and the peasants'. They were the bureaucracy's. And so-called advant-garde of the workers established the monopolistic administration, only the narrowest stratum of administrators enjoys the rights of ownership and domination.
