This would be hard to pull off for society as whole. Companies would need to hire 2x or 3x more employees (and train them). Schools need to be available, groceries etc. That being said, it does work if you are a contractor (in most cases). That's exactly what I have been doing for the past 4 years. I don't have a family, I am working 4 hours every day. I don't take unnecessary weekends. I just work from 8am to noon and call it a day. Afternoon is spent for sports, reading, social activities or just tinkering.
