The US is in much worse shape than most are willing to admit or accept, but the US has the global reserve currency it gets to abuse. That changes the game dramatically for the US. If the Eurozone had properly integrated its system, they might have stood a better chance, as it would have been easier to inflate, issue Euro bonds, and buy a lot more time as the US is doing. The EU is half a properly integrated system.
However, you refer to the US Dollar vs the Euro, but then you pick one specific country on the bond yield. Why not pick Switzerland? They have negative yields.
How about the bond yields for Spain, France, Portugal, Italy? France is going to explode next, so we can throw them in as well.
