Theoretically it's fine, why not. In practice, who would opt to coordinate twice as big group of people with halved worktime?

Why don’t we have half as many people working 80 hours then?

Because employers aren’t generally willing to pay the premium necessary to get workers to do that. In some fields they are and the workers do, e.g. law, investment banking, medicine.

That's the big problem. If you cut your work week down to 20 hours, it can be tough to get anything done at all. The amount of meetings is not going to decrease because (most) managers need to waste other people's time to feel important.
