Imagine a world in which most people worked only 15 hours a week. They would be paid as much as, or even more than, they now are, because the fruits of their labor would be distributed more evenly across society. Leisure would occupy far more of their waking hours than work. It was exactly this prospect that John Maynard Keynes conjured up in a little essay published in 1930 called “Economic Possibilities for Our Grandchildren.” Its thesis was simple. As technological progress made possible an increase in the output of goods per hour worked, people would have to work less and less to satisfy their needs, until in the end they would have to work hardly at all.
