100 percent spot on. It’s also a huge part of how they lost such a ridiculous chunk of blue collar workers in spite of labor leadership being solidly Democrat for decades.
Poor whites and rural hicks became the only working-class people it was still socially acceptable to openly mock in public. This was noticed and exploited by the right with dire consequences for our current political landscape.
Of course, a ton of other variables were at play as well, but the certainty that so-called “coastal elites” held them and everything they valued in contempt played a huge role in convincing blue-collar and middle-class rural whites to vote against their economic interests.
