I agree with most of what you say, but I'm not sure this is true:
I don't think it is a coincidence that they despise education and want to cut it at all levels. Education was probably painful for them and there is a sense of unity among them when they have a chance to exact some measure of revenge on the education system.
While some subscribe to the kind of anti-intellectualism that's always been a strong current in this country, I think most have nothing much against the kind of education that will help them get work eventually. Probably many would like to see their children go to college, but can't imagine that happening, given the explosion in the cost of tuition. They probably feel they have no real options. Of course the ambitious and, perhaps, exceptional among them could try for scholarships, or enlist in the military, show their stuff, and get an education paid for by Uncle Sam. Probably, though, many aren't aware of the possibilities and never gave the matter much thought.
There's also an apparent reluctance to move from economically disadvantaged areas to places where jobs are easier to find. Yes, they evidently don't want to leave family and friends. But historically we've always been a very mobile country; much more so than any nation in Europe, for example. But that's been declining, for whatever reason. Of course it can be expensive to move, but not so much for young people just starting out.
Young people, however, don't comprise much of Trump's base. Their parents do. And they feel the rug's been pulled out from under them. They've been unable or unwilling to adapt. Again, they do need help, at least in the form of people willing to listen to them.
But the alt-right crazies deserve no sympathy from anyone.
