The thing is; pure democracy does not address human greed; if one's drive to achieve and acquire could be controlled, democracy would be wonderful. The problem is that humans are avaricious and not able apparently to control their tendancies to acquire for themselves with no concern for mankind. Hopefully socialism (government controlled business) might address this problem.
The "fat cats" on Wall Street have fallen victim to this credo; while "Main Street" blindly believes what they are told by those who will profit at their expense.
