Some people start startups in the hope of becoming much richer than what they were before. Most of the people for whome that is a major motivator are gambling, as your risk of failure is massive, and chance of that big payoff is ludicrously small.

If you want to become much richer than before, the more rational approach for most people is likely to be to work harder, live frugally, and invest everything they possibly can set aside.

I'm not so sure we'd be worse off without those few people whose only motivation for a startup is that they care so much about the potential payoff that they'd not start a company if they couldn't strike it big.
