The thing is: When you're the kind of person that is able to amass m-/billions, you're unlikely to be very altruistic. Most of these people had to, excuse my language, fuck over people (workers, customers, investors, the larger public) along the way in various ways. You simply can't be a billionaire without some kind of severe exploitation and it is unlikely that, when you have no qualms doing so in one area, it is unlikely you care about people's livelihoods etc. in other areas (there are some exceptions ofc, Bill Gates comes to mind). Jeff Bezos is a perfect example: The richest person on earth has donated what amounts to a few cents for an ordinary person but with great public fanfare. Not even during the COVID-19 pandemic, he views it as necessary (cf. with Jack Dorsey, donating 1/3 of his wealth).
