That's your neoliberal take. Personally, I'm a little dubious that wealth created is 1:1 with social benefit created. But to say that his bank account benefits nobody would be a misrepresentation.
For whom?
Bear in mind this is the extremely idealistic neoliberal take.
Yeah it certainly is
I'm not sure I understand what you are proposing as an alternative. Taking Bezos assets to do something with?
Sitting on cash is expensive, due to inflation and taxes. It's generally better to re-invest. People are generally compensated as a function of the value they add to the company. If someone else can do a better job for less money, it would be in the board's best interests to hire them.
I do agree, though, that unwise expenditure of resources (mansions and watercraft, et all) should be criticized, though not high net-worth per-say. The problem, though, is that the common man is also guilty of unwise expenditure of resources. E.g. taking a vacation instead of providing life saving vaccines.
Maybe I'm underestimating how many rich people the world has, and how much money they have. It just doesn't seem like did have enough to make much of a difference.
