This article from the Washington Examiner takes a look at how Logan County, WV has been coping with the decline of coal. Short version: not too well. I'd only add that I think they leaned a little too hard on regulations and not hard enough on market forces when talking about what brought on the hard times. Still, it's hard to say that the situation is anything but bad.
This is an example of why Congress needs to put up or shut up on coal. Places like Logan desperately need some kinds of transitional assistance.
NO SHOCK HERE. Inequality is getting way worse.
