I don't think that the top 100 richest people is a good dataset. You can be extremely rich without making it anywhere near that list. While a lot of those top 100 people made it to that list by starting companies, I'm curious how many of them did so by leveraging family or inherited wealth.
To make it on that list, you have to have succeeded at such an extreme outlier level that almost by definition almost everything had to have gone perfectly. That takes a lot of luck and advantages, such as family advantages. I'm not saying that detracts from what they accomplished, but they can't take all the credit either and it's not reproducible.
