It’s never been easy to make a living in central Appalachia’s narrow valleys. Without coal, it’s become a whole lot harder. Mining jobs were some of the best-paying in the area, and the industry supported an array of other professions, from truck drivers to personal injury lawyers. Today about 9 percent of eastern Kentuckians are out of work. Thirty percent live in poverty, according to the most recent federal statistics. Rates of drug overdose deaths, cancer, diabetes and disability are high. President-elect Donald Trump has promised to rejuvenate the coal industry by renegotiating trade deals and rolling back environmental regulations. That might bring back some jobs, but it won’t bring back the employment levels of the 1980s or ’90s.
