Amazon also wouldn't exist in their current capacity without all their warehouse workers. I think the idea is that Bezos could have either sold some of Amazon stock over the years and paid his warehouse workers a better wage or he could have put some of his shares into an options pool for his warehouse workers. If he did that maybe he would only have $10B in wealth today, but many warehouse workers would be better off.

Instead, he kept all those shares and has more money than he could ever spend and many warehouse workers have worked incredibly hard and been unable to build any wealth over the years.
