I did this essay and my approach was similar to the "Nazism as totalitarianism" question. I went for a mixed response like this:
Thesis: Hitler played a central role in the Nazi state and had near total control, but he didnt always exert his power and he lacked economic power
Point One: Hitler was in charge and no one really contested his power (i.e. Fuhrerprincip)
Point Two: Hitler was not really involved in the day-to-day administration of Germany. His focus was on foreign affairs and military issues
Point Three: Hitler didnt have much economic control, as German industrialists retained their power as a result of a deal in order to get their support for Hitler's rise to power
I think I had another paragraph, but I cant remember what I wrote.
