In the early 20th century, eugenics was widely supported among the educated classes all across the West. Eugenicists fancied themselves benefactors of the human race, putting to use the most cutting-edge science to eradicate human suffering, and to “improve” the human race.
By giving nature a helping hand, carefully encouraging the reproduction of the “fittest” members of the human race, and discouraging the reproduction of the “unfit,” eugenicists believed they could rapidly create a race of strong, healthy, and super-intelligent human beings. No longer would the state and society be burdened with “moral degenerates” (the memorable term used by eugenicist Margaret Sanger), the mentally disabled, and those prone to costly and painful diseases.
