There's more to it than that. Hitler did scapegoat the Jews, but that was just piggy backing off a preexisting sentiment that existed in the German population. The Jews did play a role in the defeat of the Germans in WWI, and the German people didn't forget it. Interesting story, Hitler was an intelligence officer who was assigned to watch a small band of anti-semites who were causing problems at local bars. After listening to them for an evening, he stands up to give his take on it. He leaves basically the leader of the NAZI party.
