The land of desire

The Roaring Twenties remade American cars, music, movies, and ideas of pleasure. Henry Ford's assembly line and the spread of buying on credit put automobiles, telephones, and appliances into ordinary homes. Americans, as one historian put it, turned inward.

Historian Lawrence Glickman writes that Americans began “enjoying the private pleasures” of the era and showed “indifference or cynicism to the well-being of the public sphere.” William Leach named what the country had become: the land of desire.

People wanted goods, and producers hurried to make them. But one force pushed consumer culture further than cheaper cars or easier credit could: advertising. During the decade it changed from announcing what a product did to suggesting who you might become.

II

The engines of consumption

First, the machinery had to fall into place

Henry Ford split car production into stations along a moving line. Each department built one part, and the whole car was assembled at the end. Output rose as prices fell, until working-class families were buying Fords by the thousand.

Automobiles produced 1,250,000 1919–20 → 1920–21, as prices kept falling
Tractors produced 200,000 1919–20 → 1920–21, more than doubled
Personal savings rate 4.4% 1898–1916 → 1922–1929

Installment credit did the rest. Families that once saved for years could now buy with a down payment. By the mid-1920s, buying on credit had stopped feeling sinful, and the money Americans used to save went into their driveways.

III

The age of thrift

Before desire, there was discipline

The change is easier to see against what came before it. In America before the 1920s, thrift was a civic virtue, taught in classrooms and printed on government posters.

Starting with Massachusetts in 1911, state after state made “thrift education” part of the curriculum. Schools opened savings banks, which one program described as “a developer of character.” Children used them in large numbers.

More than fourteenfold in 24 years

World War I strengthened the habit. The U.S. Food Administration printed posters telling citizens to “waste nothing.” A 1918 pamphlet, The Patriotism of Saving, called waste “the selfish destruction by one of things which many need.” Saving was patriotic, and spending looked suspect.

Advertisements from that period sold what you would expect: usefulness, meaning efficiency, simplicity, and cleanliness. The product's job was to work, and the ad's job was to prove it.

Three ads, one argument: here is what it does for you

Then advertising discovered the mind

1 act of reason for every 20 acts of emotion

An advertising agency of the time, on how people decide

Advertisers in the 1920s saw what their predecessors had missed: people choose emotionally, and often irrationally. The trade dropped what historian Roland Marchand called the “factory viewpoint,” a list of what a product did, and turned toward “the mental processes of the consumer.”

They learned to produce feelings on purpose. An ad would warn you that not owning a product made you undesirable, or promise that owning it made you enviable. When the feeling is strong enough, it usually beats the arithmetic.

The proof: it worked

The psychology showed up on the balance sheet

Revenue rose from $115,000 in 1922 to over $8 million by 1929, roughly $152 million today, on a campaign built around the fear of bad breath.

Kotex 70%

Held 70% of the sanitary-napkin market in the late 1920s while charging nearly twice its rivals' price.

Odorono +112%

Sales rose 112% in a single year, passing $417,000 in 1920, after psychology entered the pitch.

VII

A national ethos

Soon, Americans defined themselves by what they owned

The change went deeper than any single sale. The pulpit, the parlor, and the President all recast consumption as part of who Americans were.

Religion
“All work is worship; all useful service prayer.”
Bruce Barton, The Man Nobody Knows, 1925. Barton recast Jesus as a patron of commerce, so consuming became a kind of worship.
The parlor
“I'll go without food before I'll see us give up the car.”
A woman in Middletown, 1929. Neighbors were judged by “the kind of car they drive,” and 21 of 26 car-owning families had no bathtub.
The President
“The chief business of the American people is business.”
Calvin Coolidge, Washington, D.C., 1925. Buying, selling, and prospering became the definition of good citizenship.

The ledger

The nation's spending tells the rest

Across the decade, the figures moved in one direction. Identity, it turned out, sold well.

Personal care +81.5%
$615M (1919) → $1,116M (1929)
Mechanical appliances +92.0%
$400M (1919) → $768M (1929)

The inheritance

Before the Twenties, thrift was a virtue and an ad sold a product's use. During them, advertising learned to sell a self, and buying became the way Americans said who they were.

The decade ended in the Great Depression, but the way of selling it built never went away. A century later, ads still sell feelings, and purchases still say who we are.
