Thrift to Credit:
how America flipped a century-old taboo

The taboo that vanished

For most of American history, borrowing for anything beyond a home or a business was shameful, not a lifestyle. "Buy it if you have the money; do without it if you don't" wasn't a slogan. It was the working morality of most 19th-century households, business owners very much included.

Henry Ford — arguably the most consequential American manufacturer of his era — believed this so strongly that he built an alternative to consumer credit rather than compete with it.

That taboo is now almost entirely gone. This chapter is the story of how. And of the fact that it didn't disappear because tastes changed. Specific companies dismantled it, deliberately, while solving a specific business problem: how to sell more than people could pay for in cash.

Before cars: the habit already existed

It's tempting to think of consumer debt as a mid-20th-century invention. That badly undersells how old the mechanism is.

The furniture retailer Cowperthwait & Sons, founded in New York in 1807, is the earliest documented installment seller in American commercial history — selling furniture on time payments generations before anyone needed the phrase "buy now, pay later". Cyrus McCormick's reaper company financed farm equipment on installment as early as the 1850s: $35 down, the balance due after harvest, with credit losses reportedly under 5 percent. That was a well-run, low-risk lending operation dressed up as a sales technique.¹

The most commonly repeated version of this story credits Isaac Singer, of sewing machine fame, with inventing installment selling in the 1850s. That's not quite right. The innovation is credited to Edward Clark, Singer's co-founder and company lawyer, who structured the financing that put sewing machines into homes that couldn't pay $100 upfront — a serious sum at the time.²

So Singer didn't invent the installment plan; Cowperthwait predates it by half a century. But Clark's version was the first to scale nationally, turning a regional retailing trick into a business model other industries would copy. By the 1880s, buying farm machinery, pianos and sewing machines on installment was well established.³ It remained a working- and middle-class tool rather than a respectable mainstream practice — until one industry made it impossible to ignore.

The car that needed a loan

Relative to income, a car in 1919 cost roughly what a house deposit costs today. Genuinely unaffordable to most households in cash.

General Motors solved this in 1919 by founding the General Motors Acceptance Corporation, at the direction of GM president William Durant and finance-committee chairman John Raskob. Not, as the story is often told, Alfred Sloan — he sat on the executive committee but wouldn't become president until 1923.⁴

GMAC didn't lend to buyers directly. It bought the financing contracts dealers had already written, giving dealers cash to keep selling while GMAC collected the payments over time. Terms standardized quickly: roughly a third down, twelve months to pay, formalized industry-wide by 1924. The finance-company industry serving this demand exploded from about 25 companies in 1917 to roughly 1,700 by 1925.⁵

Ford refused to play. Henry Ford considered installment debt morally corrosive, and in 1923 he built an alternative: the Ford Weekly Purchase Plan. Customers deposited five to ten dollars a week into a dealer-held account until they'd saved the full price, then took delivery — installment buying with the loan surgically removed.⁶

It failed. Customers could get the same result more flexibly by saving at any bank, and Ford's market share bled to GM through the decade. By 1928, with the Model A on the line, Ford's own son Edsel and executive Ernest Kanzler overruled the founder and built Universal Credit Corporation — Ford's answer to GMAC, five years after refusing to need one.⁷

Who counted, and why

How much of 1920s America actually bought cars on credit is genuinely contested. The contest is worth knowing about, because it's an early instance of a pattern that recurs throughout this track: the industry that benefits from a statistic is often the industry that produced it.

The commonly repeated figure — 60 to 75 percent of new cars sold on installment by the mid-1920s — traces in part to a 1927 study, The Economics of Installment Selling, commissioned by GM executive John Raskob himself.

A more rigorous, independently produced estimate, from economic historian Martha Olney's peer-reviewed research, works at the household level. It puts the real number at roughly 7 percent of households financing a car in 1919, rising to about 18 percent by 1925. A real and fast-growing trend — but far smaller than the industry's own promotional number implied.⁸

Both figures can be true at once. Unit sales financed and households ever financing a car measure different things. The gap between them is a useful lesson for anything else this track cites: ask who counted, and why they wanted the number to be big.

What actually flipped

The mechanism itself — pay a fraction now, the rest later, at a price — was already a century old by 1919. What was new was the moral reframing needed to sell it at automobile scale.

A furniture buyer on an installment plan in 1850 was doing something culturally a little embarrassing, the kind of thing you didn't advertise to neighbors. A car buyer on a GMAC contract in 1925 was doing something aspirational, modern and entirely respectable — marketed as the mark of a forward-looking household rather than a financially strained one.

That's the hinge this chapter is about. Not the invention of consumer credit, which is far older than most people assume, but the industry-led project of making it socially normal to use it.

Where Plenee fits

None of this history changes the arithmetic $180,000 In, $610,000 Out: what 30 years of $500 a month does and $230 Billion a Year Is the Price of Inattention: the fees worth moving accounts over already taught. What matters is whether a specific debt is priced fairly and sized to what you can carry — not how old or how normalized financing has become.

But knowing that "everyone finances everything" was manufactured, on purpose, by companies solving their own sales problem is itself a kind of visibility. It's harder to feel embarrassed by a fully funded emergency buffer and a paid-off card, or pressured into debt you don't need, once you've seen how deliberately the alternative was sold to you as normal.

The takeaway

Installment credit is far older than the car — furniture, farm equipment and sewing machines were financed decades earlier. But it took the car industry, and one company's need to move an unaffordable product at scale, to turn financing from a working-class embarrassment into an aspirational default. GMAC and Ford's competing responses set the template for a debate still running. Even the industry's own numbers about how fast it happened deserve a skeptical read, since some were produced by the industry itself. The taboo didn't erode on its own. It was dismantled, on purpose, by people who profited from its absence.
