Some interesting documentaries about them and the birth and growth of the EU.
The Nazi economy was a form of state capitalism where the state would sell contracts to multiple corporations so that they could all have a slice, which effectively led to the creation of state-sponsored cartels. A lot of these corporations that made up these cartels continued in post-war West Germany and were instrumental in the formation of the European Coal and Steel Community, the precursor to the EEC and EU.
The corporatist economic model of Nazi Germany certainly had an influence on the EU's precursor organisations. Not socially, politically or culturally of course but definitely the economic model was transferred over after the Third Reich collapsed.
