I think that Hitler hated Jews because they controlled the big businesses and banks and didnt share the wealth with others except only in their jewish communities. He also beleived that alot of the underworld crime like drugs and prostitution were controlled by the Jews and finally, he was oppossed to the ways the Jews would have their secret meetings and conspire things. This is what I understood from his book Mein Kampf
