Main question: In an environment of "almost insane greed", how do you ethically and morally prepare to share massive wealth?
I love that quote from Maimonides, a medieval philosopher that believed in imparting of his knowledge and experience rather than just giving someone what they want/need for that time.
"Give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime."
While I do believe in sharing wealth with those that really need it, I also believe it's just as important to teach them how to obtain wealth from their own efforts.
