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.
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.
