My phone replaced hundreds of pounds of cameras, maps, and stereos, and everything it removed came off GDP. The dashboard is blind to abundance, it was built for a different world, and policy steers by it anyway.
When I bought that phone I spent a few hundred pounds once, and in return I stopped spending, year after year, on film, developing, maps, CDs, and long-distance calls. I got more capability than I’d ever had, and the national accounts recorded the event as the economy shrinking. The measurement didn’t malfunction. It did exactly what it was designed to do, and that’s the problem.
What GDP can’t see
GDP [gross domestic product, a tally of the money spent on final goods and services in a country over a year] counts transactions. It doesn’t count value. Those two things used to travel together, and technology has been pulling them apart.
GDP can’t see value that stops being paid for. When photography meant film, developing, and postage, every step was a purchase, so all of it showed up in GDP. Now a photo costs nothing at the point of use, so the whole chain of film, developing, and postage has fallen out of the accounts, while you take more photos than you could ever have afforded on film. Your benefit went up and the spending went down, and only the spending is counted. Economists call the gap consumer surplus [the value you get above what you pay], and GDP’s entry for it is zero.
It can’t see time. When a free video call replaces a flight and a hotel, GDP falls by the price of the flight and the hotel, and it records nothing for the two days you got back. In an economy where more and more output is information, freed time is the actual wealth being created, and the dashboard has no gauge for it.
It can’t tell spending apart from creating value. A factory that installs robots and makes the same shoes with half the inputs is genuine productivity, and it can show up as GDP falling, because the shoes now cost less. A company that borrows to build a showroom nobody visits adds to GDP, because money changed hands. So the measure is flattered by borrowing and insulted by efficiency. That’s backwards for judging whether life is getting better.
The statisticians do try. They use hedonic adjustment [statistical change to prices to reflect quality improvements], but it can only adjust the price of things that still have prices. It has no entry for the capabilities that stopped carrying a price of their own.
Why it was built that way
Two answers, and it matters to keep them separate.
The first is practical, and here I’m reaching into general history, so hold it loosely. The accounts were designed in the 1930s and 1940s to answer depression and wartime questions. How much steel, how many tanks, how much output could be mobilised. In a physical economy almost nothing valuable was free of charge, so counting spending was a fair proxy for counting value. The tool matched the world it was built to measure. Its main architect even warned it wasn’t a measure of welfare. The world then changed and the tool didn’t.
The second answer explains why the tool was never replaced. Our money is loaned into existence. Banks create most new pounds when they make loans, so the economy carries a debt load that must be repaid in fixed pound amounts. If prices and incomes broadly fall, those fixed debts take a bigger bite of everyone’s income, people and firms start defaulting, and the failures cascade through the banks. So the system needs total spending to rise every year, no matter what technology does to real costs. A dashboard that measures spending, plus a standing target of making that number grow, is exactly the instrument panel that system requires. GDP survived because it measures a thing the debt structure needs, a bigger total spent on goods and services every year. Whether it measured wellbeing well was beside the point. And once a number becomes the target, it gets managed to hit the target, so it ends up telling you more about the policy than about your life.
What happens when policy steers by it
Technology succeeds, so real costs fall and people need to spend less to live the same life. The dashboard reads that as weakness. Policy then responds as it would to genuine failure. The central bank makes borrowing cheaper, and the government and the banking system create more money and credit to push spending back up. Technology on its own would cut prices by a few percent a year. Hitting a 2% inflation target takes enough new money to cancel the entire natural fall and then add 2% on top. You’re on a walkway moving backwards. Walking hard only holds you still. To get prices rising by 2% you have to run, and the walkway speeds up every year as technology compounds.
Instead of recreating the old spending, the new money flows into whatever can soak it up, mostly houses and shares. So asset prices inflate while wages lag, and the person who owns little watches the cost of living rise faster than their pay. Rising prices and falling real wages are the same event seen from two sides.
Meanwhile the debt keeps growing faster than the growth it buys. In the two decades to about 2020 the world added roughly 185 trillion dollars of debt to get about 46 trillion of measured growth. Each new pound of borrowing produces less real output than the last, which means more and more of the “growth” on the dashboard is just the debt itself being spent.
Then the loop feeds itself. The new money pushes firms’ costs up, so they automate faster to protect margins, which deepens the very price falls the policy is fighting, which demands more intervention. Capital flows to the wrong places, because subsidised borrowing makes value-destroying projects look profitable on paper. Firms that should fail are kept alive by cheap credit. The companies closest to the new money compound their advantage, so concentration rises. Renters fall further behind owners, people feel cheated without being able to name the mechanism, and politics turns zero-sum. And on a finite planet, a system that must force spending upward every year keeps us buying things that efficiency would otherwise have made unnecessary.
The worst of it is that we lose the ability to see abundance at all. Your phone made you richer, and the accounts counted that as the economy shrinking. The dashboard kept reading growth anyway, because borrowed spending more than covered the gap, so your gain sits buried inside a total that never stopped going up. That’s why the “productivity slowdown” looks so mysterious, and why the inflation versus deflation debate goes in circles. Both sides are measuring with a unit that’s being stretched to keep the debt serviceable, and every calculation built on a false measure inherits the error.
Four reasons to trust the number anyway
“GDP is still the best single indicator we have.”
Best available isn’t harmless when the errors all point one way. GDP systematically undercounts abundance and overcounts debt-fuelled spending, so steering by it biases policy toward forcing spending up. A compass that’s always off to the same side is worse than no compass, because you trust it.
“People still pay. The phone itself wasn’t free.”
The device is one purchase where there used to be several, each with its own replacement cycle. The accounts lost the film and the developing year after year, and the camera, the maps, the CDs, and the player each time one would have been replaced. Hardware cycles exist, but the cost per use of what the phone does has collapsed toward zero, and per-use cost is what your life actually runs on.
“If GDP fell, we’d be in a depression.”
In this system, yes. That’s the trap, not a defence of the metric. Falling prices wreck a heavily indebted economy because the debts are fixed in pounds. But that’s an indictment of the debt design, not of cheaper goods. Falling prices from better tools raise living standards. Falling prices from a credit collapse destroy them. The current system responds to both the same way, because it can’t afford falling prices of any kind.
“Measured productivity growth is weak, so this tech-deflation story must be overdone.”
Part of that measured weakness is this exact gap. Output that becomes free drops out of the numbers. The slowdown is partly genuine, because cheap credit keeps low-productivity firms alive, and partly the ruler failing.
The way out of the fog starts with measurement. Judge the economy by purchasing power [what your money actually buys] and by time, not by the flow of spending. The flight and the hotel are the price, and the two days are the wealth. Ask how many hours of work a home costs now versus a generation ago, and the picture looks very different. And to do that properly you eventually need a unit nobody can stretch, because you can’t measure a plank with a ruler that changes length. That’s the role I’d argue bitcoin plays in this story, but nothing I’ve said here needed it. What the phone does got cheaper. The dashboard counted that as a loss. Policy fought your raise. That much you can verify from your own pocket.
