I think back to Bill Maher's comment after Trump's election, that he wished the US economy would tank in order to force Trump out. The fight between globalism and nationalism is real, trillions of dollars and personal power are at stake. I wouldn't be surprised if all this is planned. Biowarfare extended to economic warfare...
But have no doubt Trump will prevail.
Oil down 30% is good for everyone except the independent oil companies. The big ones are mostly marketing and distribution, and this lowers their costs as well.
The independents that do most of the exploration and drilling in the US will be hurt by this, because it's no longer profitable for them to take the risk. In the long run, it will reduce our independence from foreign oil and more vulnerable when the price goes back up.
