What is so special about coal miners? Tons of other industries have undergone or will be soon bigger shifts in unemployment. Retail workers have been hit hard by online shopping. Taxi drivers have been hit by Uber and Lyft and the like. Truck drivers will be hit by self-driving trucks. Factory and warehouse workers have been hit by automation, which will only continue. I don't feel like we "owe" coal miners anything more than we owe other people who are industries facing declines. That said, I agree with most of what you are saying - technological innovation and other changes are hitting certain groups of people fairly hard and we, as a society, need to do more to help them transition to other careers.
