Capitalism vs. Marx

I had always been under the impression that the reason communism failed was that they did not create incentives to keep their economy competitive because people were wasting too much time doing things that were not productive. This week while we were going over Marxism I realized that even in capitalist societies we waste a lot of time and that in fact it actually takes very few of our total resources to maintain the basics for our entire population. While our history books say that in the battle between the two economic systems that capitalism came out as the victor but maybe that is only because they were the more aggressive in a dog eat dog struggle that ended up corrupting the true values of communism. In the end you just have to look at the roots of the words capitalism and communism. What makes you happier? Community or money?
