Interesting I have friends and family who work at sand mines that supply the sand for fracking. The companies they work for are still expanding and they have more overtime available than they can take. I'm not sure on the long term future of fracking but in the short 5-10 year span it doesn't appear to be going away based on how much infrastructure these companies are adding right now and how much land they're buying…
Not that your friend and family are wrong, I've just worked in extraction companies that were expanding and short on labor, then 12 months later were reviewing their options for bankruptcy. That isn't a great metric for corporate health.
