Being born into money is somehow different from the others?
Wealth is a proxy for one of the other talents. Wealth has always played a role in our selection process. Smarts, at some point, lead to an accumulation of wealth. Wealth signals, a lot more often than not, good genetic material that was awarded in previous iterations. Wealth offers the carriers of this material a better chance at survival, even if the current generation has regressed to the no-good-frat-boy mean. And if the chances are not availed, wealth is squandered in a few generations.
The idea that the wealthy, but dumb get a free ride, ultimately jeopardizing the entire system is foolish. There will always be smart people around to either guide them and their finances for a percentage, or fleece them and penalize them for their ignorance.
Enron filtered aggressively for morons. A fat lot of good it did them. A society is only a larger collection of vested interests.
