And are people willing to take a 20% pay cut? I would doubt many people could afford (or wish) to do so.
The entire premise is absurd, which is what I was pointing out.
I'm working 4 days a week, and that's working very well for me. So is my wife. So is my brother, and are several of my friends and coworkers. I strongly recommend it. We should be demanding better, and not discourage each other by saying it's absurd to want a better life.
