“I expressed my doubt that Fracking was going to save the whole US economy by itself!! How can this be?”
If the price of oil had stayed at a profit making cost, they would be right. However, all fracking stopped months ago due to the low price of oil - fracking drilling costs more than normal oil well drilling. The engineer I know who worked for Baker Hughes, sitting at their wells to fix any computer problems, was laid off three or four months ago. He hopes to teach physics at a community college for this fall. If that doesn’t work out, he has a job problem. There are many more like him who are out of work now.
There in lies the problem ‘IF’.
