The next time someone complains about "greed", ask them what they mean by that word - it's a great start to an eye-opening conversation. in a world of purely voluntary exchange, "greed" is meaningless: people only get rich if they bring value to others. you might _want_ more than you can get, but you can't GET it I'd nobody gives it to you. so traditional "greed" is nullified before it gets anywhere.

people who talk about "greed" are most likely actually mad at coercive structures that entrench monopolies which could never exist in a free market.
