That's just not accurate. The US produces and exports a wide variety of petroleum based products and lots of oil as well. We import a lot of heavier oil, because we have the capacity to refine it (unlike most nations) and export a lot of the easier to refine stuff.

And, the US industrial output is at its highest point ever.

Here the story is that our product has peaked around 2000, and has been doing down ever since.
At the end of the day the perception that economic output is dropping (slope) is valid if you consider it on a per capita basis. Now I'd you consider that the jobs and profits aren'disturbed equally, you can see why Trump won.
Eh, not really. Services and other tertiary industries are just as much "production" as a factory or a mine is. The US government, and US citizens, are not much more indebted than average. You don't "run out of money" by buying foreign goods.
Oh - and btw: the US likely not only refines most oil, it also consumes it: the US have grown to a country based on consumption, spending and borrowing, but not on producing anything. So if goods only come in and money only goes out, there comes a time where the money is gone. And that is when the trouble starts...
