The irony is that the US has been running up debt for decades upon decades. The US economy is equivalent to someone that has an unlimited credit line, who pays absolutely nothing while continuing to spend lavishly.
This article does not bring any new information or shed any light on the truth about our global economy, such as the creation of externalities that deprive human beings of basic rights. All this article does is present an old narrative (the financial news equivalent of race baiting). Grab the datasets yourself, do your own analysis, and don't listen to yellow journalist rags like this which are clearly promoting an agenda.
GDP, PPP, etc are metrics which have a low signal-to-noise ratio, because the speed with which capital moves renders any units to measure economic output meaningless. USD is still the reserve currency for most of the world (at least for the countries who account for the lion's share global economic output). Even if that were to change to RMB or [insert fiat currency], the current corrupted system will continue to exist and exploit. Do yourself a favor and become educated about cryptocurrency. Learn why this current global economic system is corrupt and a new form of enslavement. Then you'll realize that we don't need central banks. You will realize that you are not a child that needs to be constantly monitored by a nanny state. And so your enlightenment begins.
