Side question: does anyone know the origin of “dentist” being shorthand for “someone who is fairly educated/wealthy and thinks they’re sophisticated, but is actually just dumb money”? I’ve heard it quite a bit, curious about where it comes from.

A self-reinforcing meme, I'd imagine. The more you hear it, the more you're likely to use it as an example. I've certainly used the phrase "dentist from Ohio" a few times myself — no offense meant to dentists and Ohioans.
