Like zero interest rates from the Fed, the dollar as reserve currency artificially props up our economy."
I don't think "collapse" is the right word.
"Restructure" might be better.
As the US dollar loses relative value, compared to other currencies, US exports become cheaper to buy and so we'd expect them to increase, which will increase US manufacturing jobs and jobs in services which can be exported.
At the same time, our costs for imports will increase, thus reducing our imports and forcing us to make more of our own stuff, which again will increase our own jobs in manufacturing and services.
We will be forced to balance our books on imports & exports, and also, hopefully, on government spending, to begin paying down the massive debts decades of "free money" have acccumulated.
Yes, no doubt a period of difficult adjustments.
But, long term, not 100% a bad thing.
While I tend to agree with you about the restructuring that could happen I think the point that was made above still needs to be thought through. The “debt ceiling” debate is, for now, a matter for DC to decide but without the need to hold dollars suddenly people won’t be as willing to own this debt. One day, it won’t matter how high the debt ceiling is, no one will buy the treasuries and securities they need to in order for the debt to be serviced. The cuts the “right” were asking for are probably going to be forced on the country, and more, once the loss of dollar supremecy decreases your global sway.
It all depends on how quickly it happens.
