I expect this to go on and on. Eventually, as the collapse of the US in international eyes becomes more clear, it SHOULD be expected to accelerate a lot.
Most of the attempts to explain “inflation” fail pretty fundamentally. Keep in mind, government schools and even private schools which are ultimately under government control, have incentive to tell the government narrative in economics -- not the narrative bucking truth. Yes, pull and push and supply chain issues DISTORT prices. Yes, "too much" currency printing underlies most “normal” inflation (but even 1 dollar is "too much" in the end).
But, ultimately, ALL fiat currencies are a FRAUD supported by "beliefs" no more real than Santa Claus or living forever. All empires come to an end, and the endings bear remarkable similarity, if you look at the big picture.
And all fiat currencies (but not precious metals based currencies) eventually go to ZERO. And toward the end they proceed toward the asymptotic collapse with exponentially accelerating speed.
The petrodollar/SWIFT system is coming to an end. That is – and always was — inevitable. The US empire is in open collapse...and our fiat with it. Even that will become more and more and more apparent as we get closer and closer to the crescendo end. And, even under moral and smart leadership, much of the pain must be borne, not dodged nor put off.
I am mostly still hoping we can somehow save the Constitution and our "souls" in the end. If we can, we can potentially rebuild core integrity ... and ideally even better than before.
