Yeap... the US chooses Trump and the world has to put up with him. But in the end, the noise making machine is very funny and glorious as long as you have a job and you can pay your basic supplies. But if the inflation really kicks in and the world starts de-coupling from "the problem" and working closer with China, the long term will be anything but a joke.
Isn't what you described already happening? Trading oil exclusively in USD is no longer a reality, inflation stats are not telling the truth, and China has stronger relationships with many parts of the world.
