The United States produces so much more in terms of GDP than the next largest nations that it's a stretch to compare them. I think the fact that we produce more than 2X what the next largest single nation produces means that debt may function differently for us. The global economy is complex enough that relative position can mean more than short term profit and loss.
Debt is a bad thing. But the debt ceiling we just fought over extending represents 1 year of USD GDP. In everyday terms, someone expected to make $100k per year being $100k in debt. To me that sounds more like a student loan than a national crisis.
Should we make changes, cut spending and increase revenue? Sure. But we should also keep the bigger picture in mind, and look at our debt as it fits into the context of a global economy.
