JD Vance would be an interesting candidate. I read his book, Hillbilly Elegy and liked it quite a bit. He grew up that family brand of Appalachian poor from Kentucky that moved to small-town Ohio to get work, but still went back a lot and kept their culture. He went to the USMC, then summa at Ohio State, then Yale Law School, and humorously recounts the social niceties he needed to learn to succeed at the last of those - that it was important his belt matched his shoes, which would never have occurred to him - in addition to the academic excellence. Though he never says it this way, it's pretty clear that people just plain like him.
The author of the piece, Henry Olsen, is one of the few at the Washington Post who won't make you crazy, Sam. I know you're suspicious, but you'll just have to take my word for it.
