I've gotten to the point where it feels like we need a Net Worth Limit. Cap it at $250 million let's say. The rich still get to enjoy a post-scarcity lifestyle, and the rest of society doesn't hang in the balance of whether our billionaire gods are benevolent or not. I doubt Jobs, Zuck and Gates would have said "Forget it" if they knew they only had the opportunity to acquire a quarter of a billion dollars. And if they did, they are probably not the sort you want to have more money than that anyway.
