The problem (used loosely) really isn't the debt we currently have because it's at close to 0% interest. It's that the debt is almost all short term and a big chunk of it (multi trillions) become due each year because we're riding the rates.
Each percent rise adds another trillion to the debt. print more paper. rinse. repeat.
