White collar men are all fascists in waiting, after all.

Who were the primary class of people drawn to the SS and the SA? At least in the SA's case it was working class to lower middle class people.

Also, so many reds (as in communists) became fascists it was a meme in Nazi Germany.

I don't think white collar tech workers are uniquely predisposed to fascism. Blue collar tradesmen are more likely to be disposed to it and capable of getting their hands dirty.
