It's hardly surprising that this would be a problem any immigrant community suffering from extreme poverty, deprivation, and discrimination.

I recommend two additional sources on the subject of Jewish prostitution in the early 20th century: The Maimie Papers -- a correspondence between a wealthy female philanthropist and Maimie Pinzer, a Jewish prostitute living in Philadelphia and recovering from a morphine addiction. ("The Maimie Papers is Maimie’s side of that correspondence, a ... unique account of the life of a woman of the streets and her inspiring transformation." ); also Hugh Nissenson's (1976) excellent, vividly imagined novel, My Own Ground (set in the Lower East Side).
