If cleaning latrines was the only job we couldn't figure out how to automate, we could probably work one week a year cleaning latrines and the rest of the time doing whatever. Which would be fine. Obviously people have to do jobs and some are unpleasant. I'm not convinced that 40-hour work weeks or longer are necessary for society to function.
