I think there's certainly some of that, but not as much as you'd think. At least, not from that particular group.
The thing to understand is that, for decades, those folks that worked for GM, or the paper mills, or other industrial jobs, always saw themselves as special. They had more money, more vacation time, better benefits than folks in other jobs. If you chose to go to college, you were wasting your time and money. If you worked in another, lower-paid career, you were either a sucker, or too lazy to do 'real work'. Minimum wage, service jobs really *were* for teenagers, or for retired folks or housewives who just wanted something part time, to earn some extra spending money and kill time.
When it all started crashing around them, and more than half the town was laid off, somebody had to be to blame. You saw the guy in the video blame 'college educated managers,' without ever asking himself (or being asked) who sent those managers? Who made those decisions, and why?
All they knew is that, suddenly, they were out. They were expected to retrain, but nobody could tell them in what field, and everyone they were speaking to in State/County offices, the colleges and tech schools, new prospective employers, were the kind of people they'd looked down on for not knowing about 'real' work. It was humiliating.
(And, it has to be said, the snobbery worked both ways. I remember my mother grumbling about how all these 'mill rats' care about is money, but saw no shame in their ignorance, etc; we may have been relatively poor, but at least we had *standards*...)
So then, for another 20 years or so, those folks continued to struggle, along with most of the rest of the private sector, while the only group who still had any sort of guaranteed job security and benefits were public sector workers.
It was absolutely no surprise, then, that in 2010, Wisconsin elected Scott Walker, and began an all-out war on public employees, hamstringing their unions, calling them overpaid, greedy, spoiled, etc., and extending that opinion to anyone in any way involved in government or public service.
That's the context here. That's why Wisconsin voted for Trump, and I'd be surprised if the same hasn't been true in MI, PA, etc.
