Depends on what people your talking about. People working wage jobs might retire early if they work really hard and save the extra. Salaried workers really don't make that much more for working themselves to death. Bonuses might be higher, promotions might be a little quicker. Or they might not. Certainly working 80 hours will not result in twice the pay for most salaried employees, not even close. Working more efficiently (and politically) is a better route for most if not all salaried employees.
