What in interesting question.
As I see it, to understand what really made Hitler tick would take a book to explain, and many have been written, not least of all his own, Mein Kampf'.
Hitler distrusted almost every one at some point in his life and blamed the state of post-war Germany on all kinds of things and people. Just about anyone could be called a 'Guilty Man' in Hitlers eyes.
When he was 18 he failed to gain entrance to the Vienna Fine Arts Academy, That would start to explain why he hated academics.
It was possibly when he was in Vienna 1909 and living in a mens-hostel that he started to understand the working class of the day and to dislike the Jews. When he moved to Munich in 1913 his hatred of the Jews had become more deep seated.
He hated being sold down the river (as he saw it) by the Goverment of the day (he called them the 'Versailles Dikat' - The November Criminals) when the Versailles Treaty was signed at the end of the great war. That helped to nurture his hatred of politicians in general. He hated the whole political system in Germany in the early 1920s. He saw it as weak and confused.
His hatred also got directed at the 'Weimar' system, a sort of part of the Versailles Treaty. Hitler saw this as a means by way of how the 'Betrayers' (mainly Jewish financers) of the day were able to exploit German interests to foreign capitlists. He perceived that such forces were only intent on keeping the German people under 'interest slavery' in the form of reparations.
Hitler was a complicated man with several personal axe's to grind. When, in 1929, Hugenbergs (kind of like a 1920s version of Rupert Murdoch) proposal offered Hitler an alliance and with it the support of his syndicated press, Hitler was able to really get his message across to the people.
The rest is history.
