We just had by far the most pro-union administration in decades, eg they saved the Teamsters' pensions, and in return the Teamsters didn't endorse them. Americans don't care if you respect the working class or not, they're postmaterialist voters.

But they're also "education polarized", so they definitely care if you respect people who didn't go to college. But "respect" doesn't mean you're nice to them or even that you do things for them as a group. It could just mean you don't come off like you went to grad school.
