Work fills the time you allow it to (Parkinson's law). We could all work 7 days a week. Should we? Why? You get one life. Work is like oxygen; you need it to survive, but it isn’t the point of living.
You'd need regulation to prevent people from working more.
If I want to live in a particularly desirable house, I have to earn more money than the other people who want to live there too, so I can outbid them. So I'll work harder than them to do so.
