This is where he fails right at the beginning.
The German 1% back then were the Krupps, Quandts et al., mainly not Jews; though many Jews were what we'd call upper middle class today - doctors, lawyers, university professors, bankers...part of the educated backbone of the country.
I forgot to mention the many Jewish shopkeepers (from tailor to book merchant) whose shops were, of course, the target of Kristallnacht. Again, not the 1% Krupps et al (who did very well under the Nazis).
