The ideology of communism is, indeed, a good ideal. Everybody equal, nobody suffering, etc. Capitalism is truly the opposite. You need people to suffer, when comparing them to others. Capitalism requires a lower class. Its a modern day caste system, really. The difference being you can theoretically work your way up to a higher caste.
Realistically, though, the best forms are mixtures of both. Capitalism with Socialism. That is when you acheive the best balance to date.
