I guess my point wasn't that somebody else was losing out. But that Warren Buffet could have made 1/1000th the amount of profit as he did and the world itself would not have lost out. Only Warren Buffet gains, not the world as a whole. Ultimately what value does Warren Buffet's success in terms of dollars bring to the world? Again, ignoring his eventual philanthropic choices.
Don't get me wrong, I'm not saying he is a bad person or that he is not highly intelligent or even shouldn't be successful. What I am saying is that it's hard to justify that he has added proportional value to the world that is worth the money he has made. To each his own, but if this were a world full of people who only wanted to benefit upon the production done by others, then this would be a troublesome world. Just imagine, could Linus Torvalds have chosen to turn Linux into a profitable venture? Could he have been all about the money and not about producing a truly great OS that people could build upon? I just don't think it's wise to put Warren Buffet as a success story above, say, Linus because he made so much more money. I'd rather live in a world of mostly Linus' than a world of mostly Buffet's.
Donating almost everything back to society, that does not count?
