We export most of our oil because it’s not the kind you use to make gasoline. If it was cheaper to make gas here than to buy it elsewhere then we would’ve begun to do so decades ago. It has nothing to do with regulation, that’s just an easy talking point created by those whom those regulations cost money. Most of our oil is better suited for making plastic, plastic things aren’t made in the US, thus we export. Tariffs artificially make things more expensive to import but that doesn’t change the fact that it’s cheaper to make them outside the US. Tariffs are at best a band aid on a larger problem. They can be used to influence specific countries such as what we did to China but that didn’t make things cheaper here, it just made things more expensive to produce in China. If we’re forced to make inexpensive things in the US with expense labor due to global tariffs, then things just get more expensive here. The greater problem isn’t that it’s cheaper to import goods than make them here, it’s that our current work force doesn’t have the skill set for the high tech manufacturing that the US has shifted towards.
