Americans aren't the fattest nation on earth because we're overworked. Most anyone will tell you that about 50% of what you see in any field on the average day is non-productive output. The real issue is how you spend your free time, not your work time. We waste most of it on tv, the internet, and overeating and blame work because we don't have more to waste frittering on tv, the internet, and eating.; It's pretty much the same with money - we waste most of what we make, then claim we're underpaid.
Everyone working 40 hours a week has more free time than any generation in human history. We can probably dig up such scroll in ancient Etruscan entitled "The 40 Hour Work Week - Make the Dream A Reality!"
