What We Found

Conclusions · economics · September 2026

Twenty-eight essays on work, time and money, most of them about Portugal, reduced to what they found. A century of productivity went mostly into income, not time; Portugal’s core problem is an hour of work that stopped becoming more productive; the heaviest bill on the young is the price of a home; growth is an arrangement rather than a law; and more free time, less pressure on the planet and more satisfied people are compatible, on conditions that Portugal does not yet meet.

The question

The series began with a prediction Keynes made in 1930: that his grandchildren would be four to eight times richer and would work fifteen hours a week. It asked where the time went, and followed the question into wages and profits, the State’s accounts, pensions, housing, children, immigration, and what growth is for. Behind it was one question: can an economy and its institutions give people more free time, put less pressure on the planet and leave them more satisfied? This page sets out what the essays found, in ten points, each linked to the essay that makes the case. The reading guide, Work, Time and Money, lists them all.

Ten findings

What the evidence says

1. The productivity went into income, not time. Keynes was right about wealth and wrong about hours: rich countries became as much richer as he predicted, and took most of the gain as more consumption. None of it went into idleness, and in America since 1980 much of it went to the top. Portugal did the same: the household life of 1980 now costs about half the hours of work it did, and the country took almost all of the gain as goods; the normal week fell only from about 45 hours to 40. (The Fifteen-Hour Week, Where the Hours Went, The Portuguese Basket)
2. The time that was taken came in two hidden forms. Longer retirements, as people lived longer and, until about 2000, left work earlier; and less housework, which fell for women in every country with comparable surveys, by more than their paid work rose, so their leisure held steady. Neither shows up in statistics of paid hours. (The Long Retirement, The Unpaid Ledger)
3. Who gets the income matters as much as how much there is. A quarter to two-fifths of national income goes to owners, and ownership is concentrated: of the Portuguese profits that reach households, about five-sixths go to the richest tenth, and more go to owners abroad than to all Portuguese households. Work is taxed more heavily than capital. The State redistributes: counting public services, the poorer half of adults receives more than it pays and the richest tenth pays in, net, about a sixth of its income. (Earned and Unearned, Who Gets the Profits, The State’s Ledger)
4. Portugal’s core problem is the hour of work. For thirty years an hour of Portuguese work has produced about two-thirds of the European average, and since 2013 its output has barely grown, 0.17 per cent a year, while Poland caught up. Tourism is not the cause: the stall happened inside industries, as the economy added workers faster than machines, in small firms often run by owners with little schooling. (The Two-Thirds Country, The Stalled Hour)
5. The heaviest bill on the young is a home. Real house prices more than doubled after 2013 while young people’s pay did not, transferring wealth every month from those who must buy or rent to those who already own. The main cause was not foreign buyers, funds or tourist flats, which mattered in a few places, but many more households, mostly from immigration, meeting a building industry that had shrunk by half. Cheaper homes further out are paid for in time: one in six commuters into Lisbon spends more than an hour each way. (The Rent, The Bidders, Hours on the Road)
6. The State’s largest bills are not the debt. The public debt is falling and back near the euro-area average. The larger burdens left to the young are public capital allowed to wear out for a decade, and a pension system kept affordable by paying the next pensioners a much smaller share of wages, about a third of the average wage by 2070 against about a half now. That is a policy choice, and there are others. A bill that is already being paid, but not by the State, is care for the very old: their number doubles by 2060, families, mostly women, give most of the care, and households pay about half of what is spent on it. (The Inheritance, The Sustainability Story, Who Cares)
7. The Portuguese have fewer children than they want, and immigrants are carrying the numbers. Most want two children and have one and a half, because they start late and in insecure jobs. Immigrants, now about one in seven residents, are young, work as much as the Portuguese, pay far more into Social Security than they take out for now, and account for most of the recent growth in jobs, contributions and births, though they are paid less and more often poor. (Fewer Than Wanted, The Arrivals)
8. Growth is an arrangement, not a law. Economies do not need growth the way bodies need food; the theories that say they must grow do not survive examination. But jobs, debts, pensions and politics were built on the assumption of growth, and Portugal’s stagnant decade after 2000, with unemployment at 17 per cent and mass emigration, shows what happens when it stops by accident. Each dependence can be loosened, by shorter hours, lower debt, pensions that adjust themselves and taxes on wealth, but each loosening has a cost and decides who bears it. (The Treadmill, Off the Treadmill)
9. GDP measures production, not wellbeing, and some of what is produced is waste. By most other measures Portugal lives better than its GDP suggests, with long lives and falling inequality, and by some worse, having saved and invested little. Waste is real but concentrated: food, low-value health care, products that do not last, finance that outgrows its use, and credit that went into houses rather than things that produce. It can be reduced without planning, by prices that include the costs, rights for buyers and rules on credit, with a referee to enforce them. (Growth of What, Worth Producing, The Manufacture of Wants)
10. More time, less pressure on the planet and more satisfaction are compatible, on conditions. Shorter hours raise satisfaction modestly, and the effect lasts; they cut emissions mainly by cutting income; the climate depends far more on how energy is made and priced. Many Portuguese want shorter hours, 39 per cent against 22 in the EU, but few can afford less pay, and the institutions that let people take time elsewhere, a general right to reduce hours, paid time credits, time accounts, partial pensions, are narrow or absent in Portugal. The goals fit together when productivity grows and carbon is priced; they conflict when productivity stalls. Portugal’s emissions have fallen by two-fifths, mostly by closing coal plants; the rest, in transport, farming and homes, has never fallen at the pace a 90 per cent cut needs, and its carbon price was frozen and discounted. And beyond income, what separates Portugal from the most satisfied countries is mostly mental health, trust and the lives of the old. (The Three Goals, The Fifth Day, The Duty to Work, The Hard Part, Beyond Money and Hours)

Uncertain

What the evidence cannot yet settle

Several conclusions rest on thin ground. Portugal has had no time-use diary survey since 1999, so how much unpaid work and leisure the Portuguese have now is unknown, and so are the hours of care that families give. Three surveys disagree on how satisfied the Portuguese are compared with other Europeans. Whether shorter hours raise life satisfaction, not just satisfaction with work and leisure, is not well measured, and the four-day-week results come from firms that chose to try. Whether rich countries can cut emissions fast enough while growing is disputed. Whether immigrants will stay, move up into jobs that match their qualifications and pay in more than they draw over a lifetime cannot be known for decades. And the Portugal scenario to 2050 is arithmetic, not a forecast: it assumes productivity growth the country has not had since 2013.

What follows

For Portugal

Read together, the essays point to a short list, roughly in order of how much depends on it:

1. Raise productivity: invest in capital, let firms grow, and keep improving the education of those who run them. Almost every other goal is easier with it.
2. Build homes where the jobs are, faster, and stop subsidising demand that ends up in prices.
3. Price and regulate carbon, in transport and heating as well as power, returning the revenue to the households that pay most, so that the climate does not depend on how many hours people work.
4. Give every worker a right to reduce hours and return, and consider a paid time credit and a partial pension, so that time is not only for those who can afford it.
5. Decide who pays for the care of the very old: protect family carers with pension credits and paid leave, and expand care at home.
6. Treat mental health care and institutions people can trust as part of the standard of living.
7. Make pensions and public debt robust to slower growth: reduce debt while growth lasts, apply the pension rules as written, and decide in advance who adjusts.
8. Tax what accumulates, wealth and inheritance, more like work, and steer credit away from bidding up existing assets.
9. Measure progress by more than GDP, including satisfaction with time and finances, which INE already collects.

A caveat

How the series leaned

Most essays were written to be neutral and cite their critics, but a few argued a position: The Duty to Work, Earned and Unearned, The Manufacture of Wants and, in part, The Sustainability Story. And the questions themselves were chosen mostly from one side: waste, the manufacture of wants, the need for growth. The Three Goals tried to correct for that by stating the case for growth at full strength: growth is how Portugal cut infant mortality from 78 to 2.5 per thousand, it pays for the clean-energy transition and for an ageing population’s care, and poorer countries have good reason to want income. The conclusions above are meant to stand after that correction. Readers who disagree will find the data and the sources behind every number in each essay.

On method and tools

The essays were written collaboratively with Claude Opus 5.5 (Anthropic): human specification, editorial direction and critical review; machine data research, analysis and drafting. This page summarises their conclusions and adds no new data; every number here is sourced in the essay linked beside it.
