Now would be a good time for a reminder that there is no such thing as a moral billionaire. Scientifically, sane people retire to lives of luxury with their families long before they reach that level of wealth. The only reason to seek such wealth is out of a sick desire to control other human beings. Religiously, scripture says that there are no wealthy people in paradise. In the end, they all burn. Scientifically or religiously, you do not become a billionaire unless there is something broken in your soul.
