I agree but the periods of my adult life when we had expensive oil meant a lousy US economy. (73-4, 79-80, 08-12)
The left will try to claim that this is a victory for environmentalists, but the reality is that this and the decline in coal has a lot more to do with American ingenuity (fracking) giving us access to cheap oil and natural gas. This is a victory for capitalism, not a victory for marxism.
