Out of all the rich people we could talk about, Bezos is actually one of the ones I have the least problem with. Bezos has a lot of money, but he doesn't have tens of billions of dollars of "money". His net worth is mostly tied up in Amazon ownership, and if he tried to liquidate more than a small fraction of it then it'd suddenly be worth much less, both because of increased supply, and because Amazon's value is very tied up in his ability to drive the company. Maybe we could talk about problems with a system that allow Amazon to be worth as much as it is, but for the founder of a company to be worth a lot because they built a big company, that doesn't seem like a problem to me.
Interesting discussion to be had, for sure, but not what the article is really about.
"Amazon doesn’t pay taxes, but I pay taxes" is a very good sound byte from this, even if the reasons why that's the case are obviously more complicated.
