They don't really do it "for the company" though, they get a large paycheck to do it. The other types exist, but they're typically in non-profits (like, the real kind, not the one where a small team is lining their pockets) and overwork themselves because they believe in the mission. But if you make 4-10 times the national average, and you start out in your first year making more than most people will at the peak of their career, that's the biggest incentive. You absolutely can semi-retire after five years of doing that and dramatically scale down the amount of work you do because you'll have more savings than most people will have at the end of their career.
