So what makes the stuff stores buy more expensive? Like you can create a chain of price raising as far as you want but ultimately it's just someone deciding to raise prices and that creating inflation.
Again, only a handful of countries own US debt and I don't even know how US debt interest rates are going to connect to inflation in other countries. Like China and Japan are the largest debt holders and their inflation is vastly different.
Inflating money only loses purchasing power if it's tied to the value of something else as I originally said. That was literally my original point.
And what do you mean by USD debt?
