In 1934, a Belarusian-born economist named Simon Kuznets walked into the U.S. Congress and handed them a number. It was, in a sense, the number — the first comprehensive estimate of American national income. Congress had asked for it because the Great Depression was raging and nobody could actually quantify how bad things were. They were steering blind.
Kuznets gave them sight. His framework tallied up everything the economy produced — goods, services, the whole churning machine — into a single figure. It was elegant. It was useful. And within a decade, it would be repurposed for something Kuznets never intended.
World War II changed everything. The U.S. government needed to know exactly how much industrial capacity the country had. Could we build enough tanks? Enough planes? GDP — Gross Domestic Product — became the dashboard for wartime mobilization. It was brilliant for that. You want to know if your economy can produce more steel? GDP is your friend.
But here's the twist. After the war ended, the metric didn't retire. It became the scoreboard for national success. Countries competed on it. Policies were judged by it. Leaders rose and fell by whether the line went up.
Kuznets watched this happen and was, to put it mildly, not thrilled.
He warned Congress — explicitly, on the record — that "the welfare of a nation can scarcely be inferred from a measurement of national income." He said this in 1934. He kept saying it for decades. He might as well have been whispering into a hurricane.
The problems are almost comically obvious once you look. GDP counts a car crash as economic growth — the tow truck, the hospital visit, the new car purchase. It counts pollution and the cleanup of pollution. It loves divorce, because two households spend more than one. A country could poison its rivers and GDP would register the contamination and the remediation as progress.
Meanwhile, GDP is stone silent on things that arguably matter most. It doesn't measure leisure time. It ignores unpaid care work — all those hours spent raising children or looking after aging parents. It has nothing to say about whether the wealth it counts is shared by many or hoarded by few. It can't distinguish between an economy that's growing because people are thriving and one that's growing because people are spending more on security systems.
Economists know all this. There have been serious alternatives proposed — the Genuine Progress Indicator, Bhutan's famous Gross National Happiness, the Human Development Index. None have come close to dethroning GDP. It's too simple, too entrenched, too convenient.
There's something almost poetic about it. The most influential number in modern economics was designed as a wartime instrument by a man who explicitly said it shouldn't be used the way we use it. We heard him. We just didn't listen.
Which raises a question worth sitting with: what would change if we actually measured what we say we care about?
