Genuine question: is farming a blue collar job? My (possibly incorrect) image of farming is management of heavily industrialized processes, not of rolling up your sleeves.

Careful study of farming often reveals that it's a mix of landowners (rich on paper, possible cashflow problems) and workers (usually immigrant, often undocumented, in which case they're not voting at all).

Fair point. I guess it is more like managing, say, a building or plumbing firm.

I guess what I should have said is "contempt for people outside of the laptop class" (and yes farmers may use laptops but you get what I mean).

Have you see any farmers with white collars? I haven't, they tend to wear working clothes even if they have lots of money.

Prisoner's dilemma, innit. If people are going to use "I'm working class" as an excuse for holding other people in contempt, they shouldn't be surprised to see it reflected back at them.

And contempt is one of the defining features of Trumpism/Muskism, far more than "blue collar".
