What a senseless comparison to defend your senseless and ignorant point. Just picking some random persons to compare because you don't have rational arguments. But if you want to use that bs as basis for this discussion, I'm fine with it. First of all, the story of mother Teresa is proven bs or at least partly wrong and she's not the generous person as people believe she was. Secondly, Bill Gates revolutionized with brilliant ideas, which he shared with others, not with egoism. And besides that, he's one of the most generous billionaires. He's spending billions every year for charity. You're not moving forward with egoism and keeping everything for yourself. Your pushing humanity not with stacking money, but with spending it for ideas, that help everyone, not just yourself. And Bill Gates is a good example for that. He spends billions to push his ideas, that he had to help the community. And of course he does it, to earn money and have a good life. Because that is a normal goal to have. But forgetting about the people will make your ideas inessential in the long run.
