Did Hitler really believe the Jews were the source of the problems and that killing them would solve anything?

Sure, Hitler promised those people those things. But how did they believe that killing Jews would solve the problems? Yes, I know the Jews were scapegoats. But how/why would that fix anything and how could he blame the Jews?
