Crashing seems a bit over-reaching to describe the chart above. It does look more impressive when you combine the reduced crude imports with the increased exports of refined products.
We achieve the above by actually importing more crude oil than we need ourselves, refining it while keeping the jobs and refinery capacity in the US, then exporting the higher value refined products.
Does the US oil/gas industry only employ 200k?
That seems kinda low to me.
If we aren't refining it, then someone else is, and importing it here (adding to the costs). I doubt any serious person can allege that we are using half as much gas as we did in 1985.
(Hopefully someone else can post the chart. It's embedded and interactive, and I can't figure out how to post it here.)
