As I have pointed out countless times, politicians who promise to "bring back jobs from overseas" are lying through their teeth. Most of our manufacturing jobs which are gone have been automated and are not coming back, ever.
And politicians who promise to bring back coal jobs are also lying through their teeth.
Especially Trump. He knew coal jobs were gone for good when he gave this interview in Playboy way back in 1990:
PLAYBOY: What satisfaction, exactly, do you get out of doing a deal?
TRUMP: I love the creative process. I do what I do out of pure enjoyment. Hopefully, nobody does it better. There’s a beauty to making a great deal. It’s my canvas. And I like painting it.
I like the challenge and tell the story of the coal miner’s son. The coal miner gets black-lung disease, his son gets it, then his son . If I had been the son of a coal miner, I would have left the damn mines. But most people don’t have the imagination–or whatever–to leave their mine. They don’t have “it.”
PLAYBOY: Which is?
TRUMP: “It” is an ability to become an entrepreneur, a great athlete, a great writer. You’re either born with it or you’re not. Ability can be honed, perfected or neglected. The day Jack Nicklaus came into this world, he had more innate ability to play golf than anybody else.
Trump spit right in the faces of coal miners in that interview. Trump considered coal miners to be too stupid to get another career. Trump said they don't have "it".
And when Trump campaigned on bringing back coal jobs, he knew damn well he was lying to the rubes in the mines.
He knew.
