I don't think there's a single billionaire who has that kinda money because they wanna spend it. These are people who are obsessed with what they do and if you ask me, what their companies do for the economy far outweighs what charities could do because a lot of charities and NGOs are corrupt as hell. Most countries take money in the name of environmentalism, world hunger, and homelessness and then the politicans pocket that money
That's glass half empty way of looking at it imo. Music platforms have basically made record labels obsolete for small artists who could have never found a voice if not for music platforms. Goth Babe, Teenage Priest, BETWEEN FRIENDS, just to name a few. There's goods and bads. And I think letting billionaires keep investing in their crazy ideas is better than politicians pocketing that money while posing themselves are world savers. Just my two cents though and I totally respect your pov
