ELI5: Why isn't America's massive debt being considered a larger problem?
gpt
US debt is not the same as personal debt. US debt is sold as a point of investment in the form of government bonds. It is also one of the safest forms of investment as the US has never defaulted on any of its bonds when they have come due, and they do not all come due at once. 

We also have a better debt to GDP ratio than most developed countries and half that of Japan. 

Also 60% of our debts owned by the US. Divided up among various parts of the government, corporate investments into bonds, and private citizens investments into bonds. The rest is distributed among dozens of countries with China owning about 8% of our total debt.
