In the early 1930s, the German Nationalist Party (read: Nazis) didn't start out with concentration camps; they started out with new employment laws.
Well, there was a progression. First, no new immigrants of certain types (Jews, Romani, etc.).
Then, new employment laws aimed at 'undesirables' (previous list, plus Gays) who were already in the country (and in many cases had been for generations), making it illegal or very difficult to hire/employ them.
Stop me if this sounds familiar.
So then: "It's a real shame what happened to our Jewish neighbors, but HEY Heinrich, maybe now you can apply for that promotion…"
You know what made me think of this?
