I don't know what point you are trying to make. Coal is still an important energy source for us, but we will have to move on at some point. Economies shift, jobs shift, etc
Also, there is no such thing as clean coal. I call it slightly less dirty coal.
My point is that Hillary did not ever make the clear intention to provide a new resource to the working class. She completely took the side of the environmental lobby and threw West Virginians overboard.
You are right, economies do shift but you can't just tell people that they will be unemployed and expect them to be happy about it. Hillary Clinton literally said this.
I see no reason to move away from coal but I am always an advocate for diversifying energy resources.
