Your comment got me thinking. Buffett has pledged 99% of his net worth to charity when he's gone, and has enlisted other wealthy entrepreneurs to follow suit by donating at least 50%. Will that allocation of capital produce greater good than would a lesser amount garnered through investments based not on seeking the best ROI but instead based on furthering the greater good? Honest questions, and ones that I don't have the answers to: has his contribution to Coca-Cola and Philip Morris as an investor harmed the greater good more than the $44 billion or so of his net worth that will flow to charities? Could entrepreneurs and capitalists create more good with that $44 billion than the Gates Foundation?
