Sure Capitalism is Cancer except for your know it's better than Feudalism, and any the length and breadth of the sins of Communism which have been attempted in the real world, corruption, tyranny, human rights abuse, and genocide (Stalin killed 20 million human being all by himself under the mantle of the USSR), so, until you've got something which will work better, it's the Cancer we manage.

If you think Communism wouldn't be raping the earth as Capitalism is, you really haven't spent any time studying Communism which uses ever bit as many resources as Capitalism.

If you're speaking about Aspirational Communism, that being Communism which "you know hasn't really ever been attempted in earnest before, not really you know", then you're talking about fairy tales of the world to come, and we need that just about as we do another form of Christianity.
