There are very few union mines left. Actually, there are very few miners left in SW PA. The issue is that we depend on coal for energy. Cap and trade will make energy in this part of the country unaffordable and make business uncompetitive.
IIRC, PA's not-a-right-to-work state. Are there non-union mines somehow, or just no new mines being opened?
