I was giving you a hard time. I don't think there's a significant percentage of people in finance for any reason other than money.
I am utterly fascinated with the capital markets and many aspects of finance. The returns reflect a true understanding of the markets. And yes, for the record, tech startups are in many ways less stressful than finance startups :)
As far as "altruism" is concerned, the value-add to society is wholly artificial: if our financial systems weren't structured to force retirement and pension funds to invest in the capital markets, I highly doubt anyone would say they were doing something good for the world.
