In July of 1934, the working people of San Francisco answered the question of this essay in four days flat. They folded their arms in a General Strike, and my grandfather stood in the street with his notebook and recorded the result: across a great American city, "not a wheel moved nor a lever budged."1 No banker's signature could start a streetcar. No portfolio could unload a ship. The men who owned the wheels discovered, in an uncanny quiet, that ownership is not power — participation is. The same is true on the other side of the counter. The economy doesn't run because somebody owns it. It runs because a hundred and seventy million working people show up, make things, and then — this is the part the penthouse forgets — buy them back.
Start with the government's own arithmetic. Personal consumption — the money households spend on goods and services — makes up roughly 68 cents of every dollar of American GDP, running near $20 trillion a year and above its own long-term average.2 Business investment, government, and trade split the rest. There is no "the economy" apart from this: the grocery cart, the gas tank, the dentist's bill, the back-to-school list. When economists say growth, they mostly mean you, buying things. When they say recession, they mean you stopped.
Now look closer at the engine room, because there's a paradox in it. Measured in dollars, the rich loom large: by Moody's count the top tenth of earners now drives roughly half of consumer spending.3 But measured in necessity — in dollars that move the moment they arrive — the engine is the working family. The bottom fifth of households spends 33 percent of its income on food alone; the middle fifth, 12.2 percent; the top fifth, 6.4 percent.4 Sixty-eight percent of Americans live paycheck to paycheck5 — which is a hardship for them and, in cold accounting terms, a guarantee for everyone else: every dollar that reaches them is back in circulation by Friday. It buys the farmer's milk, the mechanic's hour, the barber's chair. A dollar that reaches the penthouse, by contrast, mostly goes to sleep in an asset. One dollar works for a living. The other collects rent.
This is what every farmer at every kitchen table already knows. Wheat doesn't sell to hedge funds; it sells to households. The customer for the harvest is not the man with three homes — he can only eat three meals a day, same as you. The customer is the multitude. Squeeze the multitude and you squeeze the farm gate, the packing house, the rural bank, and the small-town main street in one motion.
The rich man can only eat three meals a day. The farmer's true customer has always been the multitude — and the multitude is broke.
If you want to watch purchasing power die in real time, stand on a new-car lot. The average new vehicle now runs about $49,800 — roughly seven months of the median household's entire income, with the average payment near $936 a month against the roughly $700 the standard budgeting rule says a median family can afford.6 The result is a customer base amputated from below: the share of new-car buyers earning under $100,000 fell from 50 percent in 2020 to 37 percent in 2024, while buyers above $200,000 grew from 18 to 29 percent.7 Since 2019, new-car sales to households over $150,000 are up 45 percent; sales to households under $75,000 — the actual majority of the country — are down 30 percent.8 Detroit's answer has been to drop entry-level models and stretch loans to 84 months, and the industry now forecasts its first annual sales decline since 2022.78 They are not losing customers to a competitor. They are losing them to the rent.
What happens when the people can no longer afford to purchase what they need? We are not guessing. We ran the experiment once, nationwide, and the man who watched it from inside the banking system wrote down the mechanism. Marriner Eccles — FDR's Federal Reserve chairman, a millionaire banker, no radical — concluded that mass production requires mass consumption, and mass consumption requires wages broad enough to buy the goods. Instead, he wrote, "a giant suction pump had by 1929–30 drawn into a few hands" a growing share of the nation's newly produced wealth.9 Working families kept the game going on borrowed money, like poker players with no chips left — and when their credit ran out, in his telling, the game simply stopped.9
Look at what "stopped" meant, sector by sector. Farm income fell by two-thirds in the Depression's first three years; by 1932, corn brought eight cents a bushel and hogs three cents a pound, against debts contracted at ten times that.10 Wage income for workers who kept their jobs fell 42.5 percent between 1929 and 1933, and a quarter of the workforce had no job at all.11 And the loop fed itself: economists studying 1930 county by county found that auto sales collapsed first and hardest in farm counties — when crop prices died, farmers stopped buying cars, factories cut workers, and the workers stopped buying food. The farm-price collapse alone may explain 10 to 30 percent of the entire 1930 output decline.12 The factory and the farm were never enemies. They were two ends of the same dollar, and when the dollar stopped moving, both ends starved.
That is the answer to this essay's question, written in foreclosure notices: take purchasing power from the many, and you don't just impoverish the many — you bankrupt the system, owners included. Franklin Roosevelt named the cure in 1932, before he ever took office, calling for "plans that build from the bottom up and not from the top down" — plans that put their faith in the forgotten man at the bottom of the economic pyramid.13 Not charity. Engineering. You fuel an engine where the engine is.
Now read today's dashboard with 1929 eyes. Sixty-eight percent of households paycheck to paycheck.5 Middle-income spending flat for three years running while the top decile carries the growth3 — an economy balanced, by its own boosters' description, on the mood of its richest tenth. Cardboard-box shipments, the humble proxy for goods actually moving to actual people, at multi-year lows.5 The majority priced out of the new-car market and into 84-month loans.7 A third of the poorest families' income going to food while grocery prices sit 25 percent above 2020.34 Eccles would recognize every gauge on this panel. The suction pump is running again, and the people at the bottom of it are staying in the game the only way the bottom ever can: on credit.
None of this is an argument against farmers, builders, or honest enterprise — it is the argument for them. The farmer needs a nation that can afford groceries. The automaker needs a nation that can afford cars. The investor, whether he admits it or not, needs customers more than customers need him; a factory with no buyers is a museum. Wages are not a cost the economy bears. Wages are the fuel line.
A factory with no customers is a museum. Wages are not a cost the economy bears — they are the fuel line.
