Communism in any form, as well as socialism is evil. Both systems are diametrically opposed to fundamental human nature.
I beg to differ. Study the animal kingdom a little harder.
There are very few, if any, species that place even the slightest bit of importance on the individual. Everything pack or colony creatures do is self-sacrifice for the good of the community.
The problem with communism is the constant battle with selfish people. Not many people care about the good of the community or the world, hence the repeated failure of communism. It's this attitude that will lead to mankind's self-destruction.
Capitalism, on the other hand, nurtures and encourages selfishness. This is why capitalist governments have, in general, out lasted communist governments. However, as time goes on people increasingly realize that if they don't start giving a @#$% about something other than themselves and think further ahead than the here and now you're going to see less and less capitalistic ideals and more and more communistic ideals.
Now, the correct thing to do is go and get a real understanding of communism as Marx intended it, not as everyone else perverted and abused it. And again I'd call you to look at much of highly socialist Europe, much of which has a better standard of living than the United States.
