"Coastal Elite" is a media term. It's a media term I've happily adapted using after growing up in Northeast Ohio listening to people on TV talk about how the "Rust Belt" and the Midwest in general is such a terrible, dirty place filled with uneducated people. Going to school in Appalachia further reinforced just how negatively a good chunk of society looks at where I choose to call home.
I do not live on a coast (although I once did), nor am I elite. But, I know many who fit the description. And, all of them took life seriously early on, did well in school, busted ass work-wise, and ended up fairly successful. What's not to like about those people again? Seems to me we need way more of those types around here in opiod land. But, we digress....
I know a lot of smart people who have never touched opioids, who have busted ass in their careers and have made a life for themselves and their families. Funny story, they don't live on the coasts, they live in what you describe as "opiod land."
I know a lot of extremely successful people in Middle America who view speaking in "Clintonesque parsing" as a way for people to sound smart without actually having practical knowledge.
While not everyone from California looks down on Middle America, a very good percentage of the people on the coasts have bought up the media's narrative about how terrible this part of the country is.

I'm a hard working 27-year old who works for a tech company. No, I don't work in the Silicon Valley. I'm just a kid from Akron and I'm very happy with Ohio's current mix of hard-working kids from the Midwest with a smaller mix of national and internal students. I have ZERO interest in this University turning into an enclave for elites who are not capable of applying their education to the real world.
