The coal communities are a particularly stark case study in this phenomenon. Those jobs really aren't coming back, and everyone seems to know it except them. Imagine a scenario a hundred years ago, where a town built around the buggy whip factory wanted to shut down the auto industry so's they could keep on making those buggy whips.
This is what's happening now, except much worse. Clownstick and his buddies tricked these rubes. The regulations will get lifted, and the streams and water tables and caves (West Virginia has the finest cave system in the country) and towns will get coal ash and chemicals dumped into them. The mines will be more dangerous, less accountable for, say, a collapse. And no coal jobs added, because again, no coal jobs needed.
Welp, that's what you get in Kin-tucky for voting for Bitch McConnell over and over again, for voting for a meathead governor whose mission is to fuck you out of your health care. Same as WV, these folks are in dire need of help and seem to not want it -- or worse, insist on voting for people who will take what little they have and gut them in the process. It will happen in other states, just give it time.
These highwaymen told them exactly what the deal was, what they intended to do. The good voters of the Real 'murka states voted for them by a landslide. So a landslide is what they get, perhaps literally, once the regulations are removed. Hope they enjoy digging themselves out.
