In the 1930s, the economist John Maynard Keynes suggested that in a hundred years’ time, we’d all be working 15-hour work weeks or a 3-hour workday because of advances in productivity. Keynes predicted that we’d all have a lot more leisure time due to our material needs being met.
Interestingly, he also referred to the “Man’s dilemma” of knowing what to do with oneself when you have so much leisure time. A “sense of dread” because people were so busy striving and not used to the “age of leisure”. How does one occupy oneself when working only 3 hours a day?
