You either missed my point, or are deliberately deflecting.
You made that statement as being praise-worthy. I just pointed out how it got that way and was not defending how those other countries you mentioned came about. So, we'll call that a straw man.
If any such study took place in the Soviet Union, it wouldn't have been anonymous, so what are most people going to say? They certainly voted with their feet when given the opportunity.
Indoctrinated, am I? I can assure you that I do not support unfettered capitalism. But, a regulated mixed economy is far more preferable to a collectivized economy. Stalin's man-made famine in the Ukraine ring any bells?
You sound like a true believer. Maybe you'd like to move to China? No, wait - they found communism didn't work either. So, the regime kept the part they liked - keeping power through totalitarian oppression and ditched the failed economic model. Of course, they didn't like the looks of a free market economy either and went with the mercantilist economy - private enterprise in the service of the state.
