@GreenSkyOverMe the USSR, obviously. Cuba, I believe, although I'm less certain of that. In the USSR they broke strikes, took worker self management away and replaced it with control of each factory with a single bureaucrat, and managed the whole economy via a top down aristocratic bureaucracy that put the workers in the exact same position with respect to the means of production as they had been under capitalism: working for someone else who owned the MoP and managed them. And so on.
