Keep in mind; this isn’t because of government policies. It’s despite them.
Its because the price of oil quadrupled from $25 to $100 per barrel, plus the development of high pressure fracking technology.
If you go back 10 years there wasn't much profit in producing oil in the Bakken shale or the Canadian tar sands, but now it is very profitable.
Good point. I am a bit amazed at the resiliency of this battered economy. Imagine if the brakes were released.
