I don't know. One does have to spend one's time doing something. There is a natural limit to how LITTLE I'd like to work, technology improvements notwithstanding. If I only "had to" work 1 day a month, I can't imagine being competent at anything or feeling like I was contributing to the world. Right now, a 4-day work week sounds nice, but a 2-day work week sounds boring. So there's a balance somewhere, varying for each person and job. But 40 hours is certainly less than people used to spend farming. It used to be "6 days a week, work from sunup to sundown."
