Certainly some of Hitler’s appeal came from his perceived creation of new jobs and pulling Germany out of the economic hole it was in. Hitler and the Nazi's get too much credit for this usually.
As Petey says Europe has a long and somewhat shameful past of dealing with minorities, the Jews amongst them. But then so do most nations and places.
Germany was before, during and after WWII one of the most educated nations this planet has ever seen. Yet the people accepted the murder of millions of people. Possibly because of that education. The thing about Hitler and the Nazis was that they were never prepared to push the German people very far, they molly coddled them. If they had kicked up a stink about the holocaust it is possible that it would have been scaled back. The idea that the Gestapo was all pervasive in German society is not true until 1945. In other parts of Europe it was active.
It wasn't riches or loot or plunder or whatever that motivated the Germans, although it played a part, it was a genuine belief that what they were doing was morally, ethically right. That Nazism was right. I am ranting. It is such a complex issue, there is no right answer, just really scary realities. What people can become.
