Would you rather be a game developer or be a male prostitute? Let's say male prostitutes make a higher salary than game developers. If it makes more money to jerk off some punks under a bridge than it does to make a computer game then why not be a male prostitute? It would be irrational not to jerk off punks under a bridge since the financial incentive would be greater. I'm not disparaging male prostitution as a profession - people have to make a buck. I just want to illustrate that there are other factors besides financial incentive which motivate us.
