(Just to be clear, I'm using EV as a pseudo-technical metaphor. But it's a surprisingly good one, and could maybe be turned into a real model.)
I believe there comes a point where a person has enough wealth and needs to re-distribute it somewhere else to produce/innovate more.
It's a statement that doesn't actually represent reality.
That's just the repetition a rather circular dogma: the market is assumed to be right (typically demonstrated by some oversimplified textbook example), so right is whatever our market does.
If you want to use Bezos's wealth to justify the value he's created, you should at least try to make an independent estimation of that value.
Unless your socialist, most people agree that more productive people should earn more. I think most discussions today around inequality center around the top 0.001% where earnings and production seem unrelated. I am not of the following opinion, but some people take issue that one can "own" a corporation and your return be greater than any individual producer for that corporation for effectively doing nothing.
