Some of you may remember Tennessee Ernie Ford’s old song. I do. When I was a kid we spent summers in eastern Kentucky with my Aunt and grandparents, Dad sometimes took us out to an old strip mine to shoot tin cans with his pearl-handled six shooters, and learn some history while we were at it. Back in the day, he told us, the coal barons had a clever scheme to enslave the local populations who worked to dig out the coal from its natural habitat.
