Not true, Bray. At the most, rich Jews were 5% of European Jewry. Ever see the movie Fiddler on the Roof? Poor, rural, Eastern European Jews were the rule in many millions. It was those that mostly went to the ovens. The real smart, rich ( and lucky) ones bought their way to freedom in the West or the US or even Palestine.
Rounding up and exterminating the rural Jews became a full time job for many thousands of Gestapo that, if used in divisions and battalions against the Soviet hordes, might have had won Germany the war. Much of the Western Allied military leaders, from Eisenhower on down, were skeptical of the Nazi’s using troops and resources to kill Jews instead of fighting as it did not make military sense to them. The fact that Hitler did, even while losing, just shows his absolute hatred. He really did hate them.
So he believed he had to break a few eggs to make an omelette. Read The Last Jew in Berlin and it will explain the extent of the Jewish control of many of the higher tech manufacturing and finance.
A big reason Hitler lost is that he killed many of his best and brightest who ran his wartime production. He made lots of propaganda films of how evil the Jewish bankers were and they were a plague on Germany like rats. It very well may have been political more than ethnic just like Stalin.
The Jews were the original 1%ers.
