Why is it so far-fetched to believe that having fun actually creates value in human lives? I think the biggest stick to measure whether or not an endeavor creates value is looking how much people are willing to pay for it, and quite obviously Trism created a lot of value. Further, I think that change is best effectuated through being rich. Money makes the world go round, and it's a hell of a lot more effective than just prancing around thinking about ways to make the world a better place out of college. Think about if Bill Gates devoted the first half of his life to just changing the world, he would have done a lot of good, but probably nothing that $50+ Billion can't overcompensate.
