Well, I'm of the mindset that in theory this process of the US being the world's source of money for international exchange can work in perpetuity, but won't. Not for for systemic reasons, but political reasons. The US lacks the political control to ensure we remain the issuers of the worlds reserve currency. We flex our military might as a way to have indirect political control, but that's a dangerous way to maintain that control as it tends to create enemies. And when the enemies grow large enough, then the political reasons to end the process arrive. When that day comes (and it WILL come), life in America will change drastically, as we will not only have to switch to exporting as much as we import to avoid growing our debt, we have to start that process while already in massive debt. It will be the most historic fall of an empire in world history. And I think it will happen in my lifetime.
