Not sure if “OG Nazis” only include the first generation, but their Children were pretty much brainwashed.
You can look up “Hitler Jugend” If you want, that organisation basically indoctrinated children while growing up. Right when humans are the easiest to manipulate.
I’d wager that, maybe, you were right.
Neither sure how to call it, nor is it a technology, more like a mindset. I am just gonna name it: “Prideful Craftsmanship”
Basically the incorporation of “useless” decorations and embellishments, to show off ones skill and maybe market oneself a little. Definitely superseded in the capitalist world. Things were just prettier or more interesting to look at, even stuff that wasn’t meant to be flashy.
But with nearly everything being made to a price point, this practice has been somewhat lost.
