I really don't think so, and here's why:
I grew up in a steel town in the rust belt that was thriving up until the 1980s. Among my peers, almost everyone's father was gainfully employed, but relatively few were doing white-collar type work. (There were plenty of those types in the region, they just didn't live in the same neighborhoods where I lived.) So the people discussed in this article are not some abstract sociological concept to me, they are where I came from. Now I live in a neighborhood and school district that is predominantly white-collar with aspirations of higher education for the children growing up there, but I still have strong ties and frequent contact with my old world. And, from my experience, I know there are many men who are simply not cut out to be "knowledge workers". I don't need an expert or a study to tell me that.
These people saw their opportunities and incomes shrink (or disappear altogether) from an onslaught of imported manufactured goods. And now, they see their already shrunken piece of the pie being taken by immigrants. The Democrats tell them, "college for everyone, go to school and be a computer progammer!"
To which they reply, "Screw you, we're voting for Donald Trump. He cares more about our interests than the plight of poor Mexicans!" (And then they turn on the TV and see some Democratic politician talking about how hateful and racist they are.)
