Russia always was capitalist, that’s kind of the point of Animal Farm. If you look at the company towns of the Kentucky Coal Miners historically, it’s the same structure as the Soviet Union: the company (or the state) owns everything and enslaves the workers. One used debt, the other pretended to represent the proletariat, but the ruling class extracted labor from the workers and only supplied them the minimum necessary to survive. Lenin was a reactionary pretending to be a revolutionary.
