I'm going to try to be fair on this one... First of all, there isn't a purely communist country in this world. the USSR, like China, were/are not communist countries. They were/are totalitarian regimes. Neither the Soviets nor the Chinese people were/are in control of industrial production or were/are they classless societies.
Secondly, us humans are communal beings by nature. If you observe animals and, for example the Yanomamis, they hunt only what's necesary. It's us, capitalists, that take part in a suicidal system of survival that will most likely be the most destructive in the history of humankind. I mean, the two main precepts of capitalism: Free flow of abundant capital and continuous growth are unsustainable goals in the long run. Everybody knows that.
So, in the short run, capitalism may be "better", but in the long run it is the least desireable option.
