All Types of Social Inadequacy:

 From Truman State's files of Harry Laughlin's personal collection of papers. Depicts the relative number of "inadequacies" among 32 different ethnic makeups. Inadequacies include feeblemindedness, insanity, crime, epilepsy, tuberculosis, blindness, deafness, deformity, and dependency.

Even before Laughlin, the United States was concerned with people entering the country becoming a tax on the government. The phrase "unable to take care of himself or herself" got replaced by "likely to become a public charge" (Nielsen, 2012, p. 103). The language is became much more vague and broadened the scope of who was and was not a worthy American. 

Laughlin was a leading proponent of anti-immigration in the 1920s and 30s. He sat before many Congressional hearings espousing the restriction of immigrants with undesirable traits for the express reason that they would be a toll on the American gene pool (Nielsen, 2012).

In modern times, a group called the American Immigration Control Foundation (AICF) which was funded initially by a eugenical society from 1937 called the Pioneer Foundation, is at the forefront of anti-immigration based on racial undesirability (Intelligence Report, 2001). 

Beyond immigration restrictions, Laughlin felt that the American citizenry itself had to be held to a higher standard as well. In this way, Laughlin's strategy for America was two-fold. Protect the borders from unwanted persons and restrict unwanted traits in people through forced sterilization (Nielsen, 2012, p. 102).

Laughlin ended up being an expert witness in the Virginia case of Buck v. Bell, which you may read about in depth here.

Laughlin received an honorary Doctorate of Medicine degree from the University of Heidelberg, Germany in 1936 largely for his work in Eugenical Sterilization in the United States which contained a 'model sterilization law' ("Nazi Connection", 2020). This law was eventually used by Hitler and the Nazis as the foundation for the Nazi Sterilization Laws. These laws precipitated 80,000 murders in Germany one year into its enactment and 300,000 murders before the start of WWII (Equal Justice Initiative).

Peter Singer actively defends assisted suicide of disabled adults and even more disturbing, the killing of severely disabled infants. He argues that these infants are undesirable, making them either a poor possibility for adoption and a burden for the natural parents. Nor does he believe that babies should even be considered people until they reach a certain age due to being self-unaware. 

Singer is a world-renowned atheist philosopher and animal rights advocate. He participates in many speaking engagements to this day and consistently releases new content. Most recently (November 16, 2021), he tweeted a blurb for a live stream discussion of ethical consideration of genetics by the author of The Genetic Lottery and Its Ethical Implications Kathryn Paige Harden. Her book takes a more liberal view of genetic engineering as a way to decrease social injustice (Coyne, 2021). Unfortunately, genetic engineering has little to do with the social aspect of injustices against humanity.
