I just don't know how anyone with that much money can look at the world and not throw most of it at making others lives better.

I can't imagine hoarding that much money because I'd be using it to buy poor people houses, build decent schools, solve hunger crisises, etc. Its an absurd amount of money that nobody needs to keep all to themselves, and it could go towards making the world a better place. There is a lack of empathy amongst the billionaires.
