I don't think it works like that. Jeff is rich in the same way that Gates was rich in the 90s. Almost all of his wealth is tied up in company stock, and selling a large portion of that would certainly affect the price and his wealth. It's not like Jeff has a bank account with 100b in it. That being said, I think the real question here is "could Amazon become the best place to work without losing money?" My guess is yes. But shareholders wouldn't like it.
