That aren't the only things that qualify as "succeed" though, are they? Most of those that are privileged succeed. They may not turn $10mm into $10bn, but they'll likely see it turn into $20mm.
I agree generally that the money & connections you start out with aren't all, but 5%? No, certainly not. We'd see many rich people fall into poverty if that was the case.

That I agree with, completely. Hard work is a multiplier. But working three times as hard with $1000 won't get you close to just working normally with $10,000,000.
> re 10 million to 20 million
It would be interesting to see actual stats on that. Doubling your money over 20 years isn't super hard. However rich people are people too with vices and whatnot. I wonder what percent of those rich people blow their money on blackjack (etc) instead.
It's unequivocally true that privilege plays an important role, and that we should strive to give everyone that same level of opportunity. But the people that succeed at the level of PG or Mozart are clearly working harder, and/or are more innately talented than their equally privileged peers.
