Say What?

Michael Moore on CNN, after being asked what economic system he advocates:

Well, I don't think that this is -- I don't think that exists yet.

I think that we're -- we're talking about usually two ideologies, capitalism and socialism. One's a 16th century idea. One's a 19th century idea. We're in the 21st century. Can't we come up with our own system that meets the needs of this new era and has democracy at its core? (Emphasis mine)

Moore's idea of a 21st century system was conceived by Ancient Greeks in the 5th century BC. And he dislikes capitalism and socialism (right) because they're too old?
