Jeff Bezos himself has not performed the productive economic activity that has generated his wealth. He has performed some labor for a corporation, similar to millions of other Americans, except that because of the ownership privileges granted to him by our capitalist system his share of the wealth produced by the corporation he works for is vastly out of proportion with the wealth share almost everyone else in the entire world receives.

the wealth is Amazon's. Bezos owns quite a lot of Amazon. the system permits this level if inequality. that doesn't mean it is deserved or desirable.
