The USD is suffering from a savings glut. The domestic financial markets are already fully developed. Any additional savings from foreign nations is not helping the USA and merely forces an exorbitant downside. Investments have to match savings. All the potentially productive investments have already been made for the current level of inflation. There is nowhere for the money to go so you have two options: Unproductive investments, reduce the savings rate.

Unproductive investments are basically the constant increase in stock and housing prices over the last decade. You're not buying those to make more money, there simply is no other place for the money to go. The only way the savings rate can be reduced domestically is through unemployment or underemployment. Unemployed people don't earn money but they still have to spend, which reduces savings.

It's a truly hopeless situation for the humans living the USA. But hey, at least the dollar is still "good".

Oh right, presidents are taking on debt to cancel the savings glut that was forced upon them. That's a bad thing.
