Hitler not only wasn't a socialist but he openly despised them

"Private enterprise cannot be maintained in the age of democracy;[…]

We are today facing the following situation. The Weimar Government imposed upon us a certain constitutional order by which they put us on a democratic basis. By that we were, however, not provided with an able governmental authority. On the contrary, for the same reasons for which I criticized democracy before, it was inevitable that communism, in ever greater measure, penetrated the minds of the German people.[…]

Two fronts have thus taken shape which put to us the choice: either Marxism in its purest form, or the other side.[6]
We must first gain complete power if we want to crush the other side completely.[...] In Prussia, we must still gain another 10 seats, and in the Reich proper, another 33. That is not impossible if we exert all our strength. Then, only, begins the second action against communism."
