A machine that finishes a job in half the time ought to leave room for somebody to go home. A definition of progress that counts only production has a different instruction: find more work to fill the hours. It measures the extra production, then treats the afternoon someone could have enjoyed as though it were worth nothing.
I think that’s a rotten definition of progress. An economy should be able to make us less busy. If the only acceptable reward for becoming more productive is a larger production target, the promised escape from toil keeps moving out of reach.
John Maynard Keynes imagined another destination. His 1930 essay on the economic possibilities for his grandchildren pictured a society wealthy enough to spend much less of its life earning a living. Becoming better at producing things should give us some say over how much producing we still want to do.
Keynes’s forecast had conditions
Keynes suggested that living standards in prosperous countries could be four to eight times higher a century later. He imagined three-hour shifts or a fifteen-hour week, with the remaining work spread widely. He also assumed no major wars and no major population increase. His horizon was 2030. Turning that conditional speculation into a promise already broken in every detail would be dishonest.
Nor can we declare that modern technology has made fifteen hours sufficient for everyone. A 2024 analysis by Edoardo Beretta and colleagues argues that American productivity remains insufficient to support that schedule at its projected level of output. The conclusion depends on what output we require, but it exposes the mistake in treating a rise in living standards as proof that a particular working week is now technically possible.
Keynes’s more durable contribution was to give production a purpose beyond its own expansion. He distinguished needs that could be satisfied from the appetite to stand above other people. A society might meet the former and still exhaust itself chasing the latter. More abundance would never feel sufficient if the test of success remained having more than somebody else.
Prosperity permits different schedules
The historical record shows that people can spend less of each year in paid work, even without settling the fifteen-hour question. Our World in Data’s compilation of historical research and Penn World Table estimates puts American annual hours at about 1,840 per worker in 1980 and 1,789 in 2023. That is a modest decline across more than four decades. In the German series, hours fell from about 1,756 to 1,335 over the same period.
These averages include part-time workers. They do not describe everybody’s weekly schedule, measure unpaid care, or prove that one country’s arrangements can simply be copied. The compilation also changes coverage before 1950, so its nineteenth-century figures should not be treated as a seamless comparison with today’s entire workforce. The useful contrast is the different trajectories among modern wealthy economies. Technology alone cannot explain those different paths.
Economic historians Michael Huberman and Chris Minns identify labor power and inequality as important influences on working time. Their account also gives geography and commuting costs a role. In separate research, Alberto Alesina, Edward Glaeser and Bruce Sacerdote argue that union-backed labor regulations explain much of the American-European difference. These are competing historical explanations, with institutions in both. Neither licenses the lazy conclusion that Americans simply love work more.
The Department of Labor’s history describes the political struggle behind the 1938 Fair Labor Standards Act, whose initial weekly threshold was 44 hours. Today’s rule requires premium pay beyond 40 hours for covered, nonexempt workers. That protection required a contested political decision. A more efficient factory could not pass the law by itself.
A dividend needs a recipient
The case for leaving hours alone sounds reasonable when it starts with meaningful work. People can value their jobs. They can also want better housing, medical care, or goods that require more production. Choosing more output can be a reasonable use of an efficiency gain.
But an observed work schedule cannot tell us how freely those priorities were weighed. A person might prefer a shorter week at unchanged hourly pay, yet face a choice between the employer’s full schedule and no job. An individual wage bargain also cannot settle the shared arrangements that make shorter hours practical, including staffing and when other people are available. Calling the resulting schedule a preference skips the argument about who sets the choices.
Distribution matters too. In its September 2026 productivity release, the Bureau of Labor Statistics reported that compensation’s share of nonfarm business output was 52.8 percent in the second quarter, the lowest in that series beginning in 1947. That figure cannot explain a century of working hours, and it does not mean workers received none of the gains from growth. It is a warning against assuming that productive capacity and workers’ command over its rewards are the same thing.
I want time people can reclaim counted among the benefits of better production. A society could choose some extra output and some extra leisure. Treating the first as progress and the second as a regrettable loss builds the employer’s preference into the definition before anyone gets a vote.
Rest should not have to pay for itself
Care makes the limits concrete. A faster spreadsheet cannot sit with a frightened patient. Shortening paid hours across an economy requires deciding how necessary work gets staffed and funded, and who does unpaid work after the paid shift ends. Announcing that the machines have solved everything would erase those obligations.
Those limits should discipline the ambition. They provide no reason to make rising output the permanent purpose of life. A society that values care ought to protect the time needed to give it. It should also recognize time spent doing nothing useful to an employer as a legitimate benefit.
Even the familiar defense that shorter hours might make people more productive leaves something important unsaid. Rest should count when it fails that test. An afternoon should not need a business case. Requiring one reduces the person taking a break to a machine due for maintenance.
Keynes called the alternative the “art of life itself”. I would settle for an economy capable of admitting that a free afternoon can be worth more than whatever else it could have squeezed out of us. The shorter week will require material capacity and collective decisions about its use. Waiting for growth to make those decisions for us is how the people buying our hours get to keep them.
