"treacherous tool of the bourgeoisie"
You really are brainwashed!
Stalin committed mass murder at a level equal to Hitler. If you kill a huge percentage of your people, then enslave the rest, yes you may see some improvements in the economic output. But the standard of living for your people will be barely above torture.
Hitler got a whole lot of work from his slave labor camps too.
BTW - The Soviet Union's economy was never close to the U.S. economy - and we did it without the mass murder and enslavement of the majority of our citizens. The only slavery that there was was ended by the U.S. Government.
Perhaps Communism did improve the standard of living for some Soviet Citizens, but that's only becaus ethe standard of living was so bad under the Czar.
Also, The German economy under Hitler was far better then the Soviet economy under Stalin. If it weren't for the Soviet's allies, the Germans would have won the war.
