Socialism, the government formation, under which communism is classified, looks very, very good on paper (I don't know about Marxism though, I read about it but it was very confusing). Everything is equal, and whatnot, but it has been proven not to work after the downfall of the USSR (Not Russia, Russia fell in 1917 and was re-founded in 1991). The only exception is China, and they still battle constant problems with censoring. Just look at North Korea and Cuba, just look at their economies, the quality of life there, and other factors that are considered when judging a country. Sorry for writing so much, I just love politics...
BTW, you shouldn't say something like that in such neglect, I'm sure you would never say that to my Russian friend would you?
