The dark parallels between 1920s America and today’s political climate (Alex Green, 3/10/25, The Conversation)
Other Americans were concerned about the possible rise of communism in the U.S., as well as the 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 the 1924 Johnson-Reed Act, a restrictive immigration policy that, among other changes, prohibited immigration from Asia.
Another pivotal movement was the Supreme Court’s 1927 Buck v. Bell decision, which affirmed that the state of Virginia had the right to sterilize intellectually and developmentally disabled people.
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 “race suicide.”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.
The U.S. politicians who lobbied for this law 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 – meaning people from Northern Europe – and their American descendants, who formed a group they called the “American Race.”
By restricting immigration from all other groups, these legislators believed they were counterbalancing a crushing period where war and pandemic had killed off what they saw as the country’s best people.
Different groups preyed on Americans’ grief about the war and pandemic and directed it against minority groups.
From Maine to California, a revived Ku Klux Klan attracted millions of followers with its belief that white people were superior to all others, and that 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 something 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 movement’s most vocal representatives.
Laughlin worked for several different 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.
Nazism is just the German version of the science of American Progressives.
