What makes those in the interior have "coastal elitist values" and vice versa?

[HillGoose]

I ask, because the interior of the nation vs. the coasts seems to be a big thing in politics now.

I remember someone on here called social liberalism with economic conservatism "an ideology of the elite" and I remember thinking "Huh, that's funny because I've literally spent almost all of my life in Appalachia or at least Tennessee and I still vibe with that ideology more than most people on the coasts probably do." And I can attest to many of my friends (ranging in age from teens to late 20s) having "cosmopolitan neoliberal" values that many pundits and a lot of the people on this website claim are limited almost exclusively to wealthy people on the coasts.

So my question is why is it generally assumed that cosmopolitan neoliberals are all wealthy and from the coasts, or that economic leftists but social conservatives are clustered in Appalachia and the middle of the country? I don't get the idea that a working class white man can't also be in favor of privatizing Social Security, or deregulation of the financial sector, or whatever you know? On the flip side, there are plenty of wealthy socialists in New York and California who want stricter regulations on everything.

I know on here I get labeled as one of the most "anti-worker" users, but I'm probably considered WWC, and Appalachian. So if you think WWC Appalachia is so "pro-worker" what results in so many of us (in my experience at least) being the exact opposite of that?
