There were Jewish neighborhoods in every midwestern city after the 1880's; 2.8 million Jews immigrated, enough to fill entire ghettos came over, 94% of them Eastern Europeans,mostly poor. The German Jews, mostly wealthy bankers and professionals, despised them, and it was years before they would share a synagogue with Slav Jews. Even as late as the 1990's German Jews would discriminate against Polish Jews.
See the book 740 Park; it has a story about the first Jew allowed to buy an apartment there, then voting to bar an eastern European Jew from moving into the building. lol
