Coal miners have already been trained. Put the miners back to work. It will lower unemployment, create more tax revenues for state and Federal Government. It may even increase sales tax revenue for cities and counties where the miners work. Why create new problems when the new solution (retraining) is actually the old solution of Jobs. Retraining is a Socialism solution to unhappy starving citizens to keep the quiet during unhappy times. New parents learned this trick by shoving food into a crying babies mouth.
