In a way, economic output is a measure of the world’s utility. So a billionaire trying to maximize their wealth through non zero-sum ventures is already trying to maximize the amount of good they do. I don’t think billionaires explicitly have this in mind, but I do know that they became billionaires by obsessively pursuing the growth of their companies, and they believe they can continue to maximize their impact by continuing to do so. Donating all your money could maybe do a lot of good *once*, but then you don’t have any more money left and have nearly abolished your power and ability of having further impact.
