The period offers something of a mirror of the current political situation.

Introduction
As promised, the second Trump administration has quickly rolled out a slew of policies and executive orders that the president says are all aimed at โMaking America Great Again.โ This takes on different forms, including Elon Muskโs Department of Government Efficiency quicklyย laying off thousands of workersย at various federal agencies, and President Donald Trump pausingย all funding for Ukraine.
Trump says that, among others, there are three groups that are making America not-great:ย immigrants,ย people with disabilities, and people who are committed toย diversity, equity and inclusionย policies.
These administration efforts began at a time when many Americans expressed an overall rising sense of dissatisfaction with theย state of the country and politics. Just 19% of Americans said in December 2024 that they think the country isย heading in the right direction.
This perspective is striking not only because it is so dark, but because it strongly resembles how Americans felt during a pivotal decade 100 years ago, when peopleโs dissatisfaction with the state of the country led to a series of discriminatory, hateful policies by the federal government.
Itโs a period of American history that I think offers something of a mirror of the current political situation in the U.S.
The Roaring ’20s?

In the 1920s, theย economy was good, the U.S.ย had won World War I, and aย terrible pandemic ended.
But many Americans did not see it that way.
They entered the 1920s with a growing sense of paranoia and a feeling that they had been robbed of something. Winning World War I had come at a terrible cost. More thanย 116,000 American soldiers diedย and twice that number came home wounded.
As the war came to a close, the U.S. โ and the world โ was in the throes of the flu pandemic that ultimately claimedย tens of millions of lives,ย including about 675,000ย in the U.S.
Other Americans were concerned about the possible rise of communism in the U.S., as well as theย arrival of many immigrants. This led extremists to introduce and implement hate-based policies at the federal and state level that targeted nonwhite immigrants and disabled people.
Among the most significant results of that political moment was theย 1924 Johnson-Reed Act, a restrictive immigration policy that, among other changes, prohibited immigration from Asia.
Another pivotal movement was the Supreme Courtโs 1927ย Buck v. Bellย decision, which affirmed that the state of Virginia had the right to sterilize intellectually and developmentally disabled people.
Discrimination against Marginalized Groups
The Johnson-Reed Act prompted a major shift in American immigration policy, based on the fear of something that former President Theodore Roosevelt and others called โrace suicide.โ
The law introduced rigid restrictions keeping people out of the country who were not from Northern and Western Europe. The immigration quotas that it established would continue to be enforced into the 1960s.
Theย U.S. politicians who lobbied for this lawย were successful because they supported their effort by presenting evidence that showed purportedly scientific proof that almost all people in the world were biologically inferior to a group they called the Nordic Race โ meaning people from Northern Europe โ and their American descendants, who formed a group they called the โAmerican Race.โ
By restricting immigration from all other groups, these legislators believed they were counterbalancing a crushing period whereย war and pandemic had killed offย what they saw as the countryโs best people.
Different groups preyed on Americansโ grief about the war and pandemic and directed it against minority groups.

From Maine to California, a revived Ku Klux Klanย attracted millions of followersย with its belief that white people were superior to all others, and thatย Black people should remain enslaved. At the same time, a group of scientists, doctors and psychologists found enormous success in persuading the public that there were scientific reasons why hatred and discrimination needed to be incorporated into American government.
Their proof was somethingย called eugenics, a pseudoscience which argued that humans had to use advanced technology and medicine to get people with good traits to reproduce while stopping those with bad traits from having the opportunity to do so.
Harry Laughlin, a eugenicist based at a research laboratory in Cold Spring Harbor, New York, was one of this movementโs most vocal representatives.
Laughlin worked for several differentย eugenics research organizations, and this helped him become successful at creating propaganda supporting eugenics that influenced public policy. He then gained a spot as an expert eugenics adviser to Congress in the early 1920s. With his position, Laughlin then provided the pseudoscientific data that gave the supporters of Johnson-Reed the claims they needed to justify passing the measure.
A Push for Sterlization

In Laughlinโs influential 1922 book โEugenic Sterilization in the United States,โ he detailed a road map for passing a law that would allow governments to sterilize disabled people.
After so much death during World War I and the influenza pandemic, Laughlin found fertile ground for making a case that the U.S. needed to stop people who might beย considered โfeeble-mindedโย from passing down inferior traits.
In the mid-1920s, Laughlin and his allies pressed a court case against a teenage woman whom the state of Virginia had deemed an imbecile and incarcerated at a massive Virginia institution for the feeble-minded.ย This woman, Carrie Buck, was incarceratedย after she gave birth to a child in 1924 who was conceived as a result of rape. If Buck, who was 18 years old at the time, had any hope of being released, the officials who ran the institution demanded she be sterilized first.
All across the country, states had begun legalizing forced sterilization. Now, this case ofย Buck v. Bellย made its way to the U.S. Supreme Court. In 1927, Justice Oliver Wendell Holmes Jr. issued the courtโs ruling, which had only one dissent. In it, he wrote that โthree generations of imbeciles is enoughโ and extended the scope of a previous ruling that allowed the government to compel people to get vaccinated to include forced sterilization of disabled people.
Buck was forciblyย sterilized in October 1927, shortly after the courtโs ruling.
While it is unquestionable that sterilization and other discriminatory policiesย found common causeย with Adolf Hitlerโs rising Nazi movement โ which used the eugenic ideas of sterilization and mass extermination โ they persisted, largely unchallenged, here in the U.S.
Some people,ย including myself, argue that the spirit of these discriminatory policies still exists in the U.S. today.
A Familiar Story
Following stalemated wars in Iraq and Afghanistan in the 2000s and the COVID-19 pandemic in 2020, theย American economy has been growing.
But sensing a grave decline, some white Americans have turned their sights on people with disabilities, immigrants, transgender and nonbinary people, and people of color as the source of their problems.
Trump regularly encourages this kind of thinking. In January 2025, heย blamed an air collisionย that occurred over the Potomac River andย killed 67 peopleย on disabled Federal Aviation Administration employees, implying that they did not possess the intelligence to do their jobs.
Trump falsely said the Jan. 1, 2025, New Orleans terror attackย was caused by illegal immigration, even though a Texas-born man drove a car into a crowd of people,ย killing 14.
At a policy level, Trumpโs administration has made significant changes to the immigration system, including takingย steps to remove legal protections for 350,000 Venezuelan immigrantsย in the U.S. And he has launched an unprecedentedย challenge to birthright citizenship.
There are limits to what history can say about the current situation. But these similarities with the early 1920s suggest that, contrary to many claims about the unprecedented nature of the current times, the country has been here before.
