I think you're missing the point.
White, blue collar voters in the Rust Belt aren't blaming technology for the decimation of the American middle class, nor are these people the kind of stereotypical redneck hillbillies you seem to be implying they are. Folks in red states have cell phones too you know, and computers work just as well in rural America as they do on the coasts.
But what's not working in rural America is rural Americans, and they're losing their jobs all over, not just in West Virginia coal mines. And these jobs aren't being replaced by technology; in most cases, jobs are getting shipped out of the country, to Mexico and elsewhere, because businesses can pay pennies on the dollar to workers in those countries versus what an American worker would make. Again, that has nothing to do with technology, but it is why white men and women in Wisconsin, Ohio and other formerly blue states voted for Trump by wide margins.
Globalization, free trade, NAFTA -- all of these bi-lateral international agreements aren't doing bupkis for the part of America where factories close and two-thirds of the town is out of work. Economists will tell you it's better to ship those jobs to Mexico and elsewhere because those places can make the same products for less money, and American consumers win with lower costs for goods on store shelves. But what the Rust Belts sees is that it doesn't matter if you can buy a pair of shoes at Walmart for $0.53 less if you don't have a job! And again, this is what's happening in all kinds of small towns all across America. When Hillary Clinton starts talking about trade agreements, all it does is piss-off people who already lost their job in the last round of trade deals. When Trump says he'll repeal NAFTA, white, rural America sees him as their champion.
Ultimately, it doesn't matter if Trump can bring back the lost mining or factory jobs; at least he says he'll try, which is far more than the establishment in either party has said for decades. And unless Facebook starts opening factories in rural America, and technology turns its engines of innovation towards helping to solve the middle-America employment problem, high tech just looks like another part of the problem, not part of a solution for the Unemployed States of America.
