To go further in this question, there is a very interesting book:
Götz Aly, Hitler’s Beneficiaries: How the Nazis Bought the German People, 2007.
In 1945, the Nazi power benefited from popular support because of the material advantages that the Germans derived from the policies of predation. This thesis must be nuanced, but it has the quality of integrating economic and social dimensions alongside ideology into questions of support for the system (social benefits, housing and employment policies). The political stability of authoritarianism and totalitarianism also stems from the negotiation between power and its populations.
