You already took that 20% pay cut. Our pay hasn't gone up with our productivity in decades. According to Keynes, we should have been working 15 hours per week by now. We're not, because we're not reaping the rewards of our work. It's all gone to the rich. That is the big thing we need to reverse.
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.
