That is not what Nazi Germany believed. Also, coincidentally, German Jews were not more rich then average, there was no persistent difference like that. They were lower middle class that clustered in the few cities. Portion of them were refugees from Eastern Europe.

Also, Germany had actually very small Jewish minority which was very integrated.
