> The only reason people work is literally for money
Theories like Hertzberg exist for a reason and show that money isn't even close to the most important thing for people to work for. If the money is good enough, there are many other factors that are way more important. Not enough money is a reason for people to leave, getting more money is hardly ever a reason to work harder. The possibility of getting more money if they work harder is a good motivator though, once they have it that stops.
