I dont really think there is a "line". I think a true market place corrects itself along with a culture in society when things go off the rails. The problem is now we have the invisible hand of media/government/big banks etc that make sure they can keep theirs and see to it that us rubes dont "correct" anything. The game is rigged in a way, but the solution is not to toss the whole system out and replace it with socialism or feudalism where we are peasants who own nothing. Our system works. Is it perfect, no.
