but you would be out-competed by people who work 5 days. The reason things like housing is expensive is because there are lots of people willing to pay higher. This implies that those people _have_ become wealthier. You would not hear them complain about being poorer (or it's an insincere form of complaint).
I don't think that's true. We already have significantly varied working hours between countries. China has 996. The US has a 40 hour standard work week and the culture is such that people often work longer hours. Whereas in Europe 35 or 37.5 hours or even less is common. Different countries have different numbers of public holidays, etc.
