Totally Moronic! (Spoilers)

You took the words right out of my mouth.

If Jimmy cracked corn and no one cares, why is there a song about it?

I think it meant the jews that were selling worthless junk were gaining a fair amount of wealth but yet still didn't bother to clean. When they'd finally worked up to owning shops and warehouses and banks - they suddenly bought opulent mansions to integrate themselves among rich.

Not surprisingly the Nazis attributed to Jews the most extreme manifestations of human existence -- as shown in the depiction of the social climb of successful Jewish merchants. If individual Jews are poor, then such shows their pitiable incompetence. If Jews succeed and clean up their acts then such shows an intent to deceive about a loathsomeness that they can never quite get eliminate. They could be cowardly and reckless; they could live in studied and deliberate isolation from the rest of humanity and yet seek to infiltrate (and, being Jews -- at least in Nazi ideology, corrupt) gentile life. They are firmly attached to the Ghetto, yet they strive to escape it.

Seventy years later about everyone sees it as too ludicrously crude to convince anyone. Yet it apparently did convince many Germans at worst to see nothing wrong about the most ghastly deeds done to Jews... and many others to see not want to know.

...The truth is that before 1933 the Jews of "Poland and Russia" may have assimilated more fully into the cultures of German-speaking countries than into any others. Yiddish is easy to learn German from than, for example, English. German culture (if not the abandonment of Judaism) was itself culture and modernity. They found no contradiction between being a German and being a Jew, often thinking such a combination the best of all possible worlds.

They also accuse Einstein of launching an attack on pure German thought with his new Jewish pseudo-science of "relativity." Ironic that Hitler might have wanted an A-bomb but he couldn't accept Jewish discoveries in physics that make the A-bomb possible.
