Yes, there's a big, big chasm in who should get "reparations". There were a lot of European immigrants that came over under the guise of "indentured servitude" where they were essentially slaves until they paid off their debt, which typically took a hell of a long time to do.
Of course, there's your example, which left me in awe as well. Miners for decades were wage slaves. Don't know how much conditions have improved in that industry, I'm hoping things are better. But, as you said, if fossil fuels are going away then it will be interesting to see what happens and they should compensate the workers that are currently doing the job, if not all of the families and descendants.
The one slim hope for our miners might be that if sleepy Joe & company get rid of U.S. fossil fuels there might still be a market on the international marketplace, but the price will be severly depressed because there won't be as much demand.
