Thats certainly the most common way people make money. What would be more useful is if you or any of the other responders wants to define what the evil/immoral acts all billionaires are guilty of other than the act of hoarding that much money to begin with. I just listed 3 billionaires whom I believe attained their massive wealth through non-evil means, so why not begin there? What would be really interesting would be for any of you to detail their evil acts and differentiate it from the non-billionaires in the same industries, down to and including yourselves.
