Perhaps, though that starts a long line of big ifs, and the wealth to solve a great deal of the world's problems already exists - a vast chunk of it just spins in various shadowy games. I tend to think there are better ways for bettering society than philanthropy though, and these vary wildly in effectiveness. In this case the millionaires in this fund focused primarily on some cancer charities. I understand that these tend to resonate emotionally since everyone is at risk, but really they are quite suboptimal ways of channeling funding relative to the needs of the world or maximising ethical return on investment.
