Ms Sanger advocated abortion for black women. The emergingly powerful abortion industry could not have its goldming (liberal and financial) potentially being assaulted
in the media through the use of race empathy. They just could not have it. Ergo, Mike Wallace steps in and propels the future PP Association into a billion dollar industry responsible for dozens of millions of murders.
Actually Sanger made it into the big time back in the 20s when she won the support of the Rockefeller foundation and others. The Rich, aka, social darwinists, wanted to keep down the numbers of the unfit, which included blacks, and the mentally handicapped. She also suppirted the KKK which in the beginning was respectable middle-class organization that hated Jews, Catholics and Bolsheviks with equal intensity. Mrs Roosevelt was a supporter.
