text: Germany paid reparations to the victims of the Holocaust and their descendants, and you basiaclly can't swing a stick in a German city without hitting a monument to the victims of Nazi crimes. The Monument to Murdered Jews of Europe is 5 acres smack in the center of Berlin, right in front of the Reichstag. So to the extant that your characterization of Jews and black Americans is correct, the answer is "because Germany apologized for what they did, while the US was busy putting up statues of confederate Generals".
