Sanger wanted women to have birth control, and not for the reasons modern eyes and ears might expect. Sure, she wanted women to be able to determine if and when they bear children. But her reasons went beyond the individual. She had much wider goals related to the population at large. As she said in this 1932 article, restricting birth control would undermine the greater good (in her view) of “social welfare and race improvement.”
Birth control was advantageous for society at large, lectured Sanger, because it could racially refine America by eliminating lesser people.
Only the wretched supported legal abortion.
