Why do you think he should give to charity, or anyone? It's his money and he can keep it if he wants.
Yeah to each his own. I have to believe he's not just holding onto it to spend it or just for the hell of it. I mean who knows how much longer he'll be around, I don't take offense to it. Ppl give away money because they like doing it, it makes them feel good about themselves. True altruism is about the rarest thing in the world, so if Steve doesn't want to he doesn't have to. And by true altruism I mean if Bill, for instance, gave away 28 billion just because, Id be amazed. I'm sure he got something out of it, he wasn't like darn I want to keep my money but I really should contribute to society I guess.
