Unfortunately, most Americans don’t care about any of this at all.
They don’t understand that more U.S. dollars are actually used outside the United States than are used inside the United States.  Because most of the rest of the world uses U.S. dollars to trade with one another, this has created a tremendous amount of artificial demand for our currency.  In other words, the value of the U.S. dollar is much higher than it otherwise would be, and this has enabled us to import trillions of dollars of products at ridiculously low prices.  The standard of living that we enjoy today is highly dependent on this arrangement continuing.
And our ability to fund the federal government and our state and local governments is heavily dependent on the rest of the planet loaning our dollars back to us for next to nothing.  If we actually had to pay realistic market rates to borrow money, the finances of the federal government would have already collapsed long ago.
