That's become my feeling as well. I've always looked at them making a ton of money without needing to start a company and become somewhat envious (none of what I actually enjoy working on seems to be startup material). Then I see two of my friends pursue careers in law after becoming attorneys, and wow, I now think my 9-5 job for a tech giant is a better gig. They're miserable.
Their work life is an unending series of zero-sum games. One path to happiness is to set your life up to minimise your exposure to zero-sum games, this is unavailable to them.
