Well said. I would guess (and it's only a guess) that people with the drive to become billionaires would find a way regardless of formal education, and that there is no recipe you can follow to reach an outlier level of wealth.
Warren Buffet observed the correlation between access and wealth. If you figure what the "rate of genius" is, meaning if genius happens let's say 1 in a 1000, then it would stand to reason that there's more successful people in China and India by the numbers. But if we look at the list of billionaires by nationality* we see the U.S. has the overwhelming majority of them - 359 compared to 28/24.
Genius does not equal wealth or even success perhaps, but I think there can be parallels drawn between them. Mr. Buffet himself said he would not have been the success he is if he were born in some place like Peru or something.
