I'll be honest and say that I've never done in depth research on communism and socialism. The most I've gotten from economics classes and textbooks is how communism is good on paper but pretty difficult to implement and control. I always remember the case in the USSR where shortages in consumer goods were rampant and many finished goods were of low quality. Then again how could a system where the rich get richer while the poor get poorer be seen as a good thing.....ah well.
