Ah stop Sid. I've seen first hand the "success" of communism/socialism in Eastern Europe over a number of years or rather the aftermath. Centrally planned economies producing poor quality goods. Poor living standards, corruption everywhere, even today doctors are still being bribed FFS. Sullen people conditioned not to challenge authority.
The Eastern Europeans were pretty quick to overthrow their communist overlords when there was a bit of momentum. So maybe they knew something that the theoretical marxists in the West didn't. And pretty quick to embrace the free market instead. It was a pity that the commy appartchiks managed to divvy up the best State assets and sell them to the evil Western capitalists. They didn't pass on the benefits to the proletariat however but they kept them for themselves.
i've also seen the other extreme of post communism and the development of a rampant consumer society with no values. But that's another story.
