As I said above: "Don't expect them to feel a sense of obligation if you're going to assume the worst about them just because they are rich."
You say that "Every single one has exploited people left and right", what evidentiary basis could you possibly have for making that statement? There are thousands of billionaires worldwide, could you name even 100 of them off the top of your head, much less explain how each and every one "exploited people left and right"?
Haters gonna hate.
