“Keynes said that in hundred years the productivity would increase so much that we would only need to work 3-day work weeks.”—“Well, I guess people have a revealed preference to work 5-day work weeks.”—Sure, smart guy. Show me where can I find the job advertisements for the 3-day work week jobs. Oh, there are none! So from the fact that I didn’t choose from an empty set you can figure out what my true desire is. Amazing!
To be fair, in surveys, most people do answer that they wouldn’t want to work fewer hours if it meant that they would get less take-home pay.
