It was of little importance that the Soviet constitution tried to preserve the political weight of the working class so that the latter had first place in representation in the state (1 delegate for each 25,000 workers, while 125,000 peasants also elected 1 delegate), when already the problem was the absorption of these workers into the conservative machinery of the state.
And once the proletarian revolution was completely defeated in Europe, nothing, not even the iron control the Bolshevik party maintained over society, could prevent world and thus Russian capitalism from taking control of the state and leading it in a direction absolutely opposed to what the communists were trying to do:
"The machine refused to obey the hand that guided it. It was like a car that was not going in the direction the driver desired, but in the direction someone else desired; as if it were being driven by some mysterious, lawless hand. God knows who, perhaps of a profiteer, or of a private capitalist, or of both. Be that as it may, the car is not going quite in the direction the man at the wheel imagines, and often it goes in an altogether different direction" (Lenin: "Political Report of the Central Committee of the RCP.', 27.3.22, Selected Works, Vol 3 page 620).
