The money will run out. Foreign countries will know the value of our printed currency
The money has already run out. We are deep in debt and things are getting worse. However, the dollar remains the world reserve currency and that will not change anytime soon. The US economy, as bad as it is, is still the world’s safe harbor when it comes to investing and protecting their money and it is also the largest thus able to absorb huge investments. How long that will continue is anyone’s guess, but I suspect we will have both left this mortal coil long before it happens.
