Somebody: Nazism was more traditional and agrarian than you give it credit for. The NSDAP received its highest vote percentages in rural Protestant parts of the country, in a few counties on the order of three-quarters of the population. On average, they did 10 percentage points better in rural Protestant regions as compared to the national average. And of course, their social base in the cities was the traditional self-employed middle class.
We're blinded by the autobahn, the blitzkrieg, and rocket into thinking of the Nazis as ultra-modern. But in reality, in social origins, they're in the same family as all the right-wing militarist regimes in the post-colonial nations after World War II. Nazi Germany had a higher percentage of the population employed in agriculture than Columbia, Iran, or Brazil today; that is to say, it was still in transition from being an agrarian society.
