Contrary to widespread claims that the U.S. government will default on its debt if the debt limit isn't raised, federal law and the Constitution require the Treasury to service the debt, and it has ample tax revenues to do this. The federal government collected $5.1 trillion of revenues in 2022, while interest on the debt was $775 billion, or roughly 15% of revenues. This reveals that the government has plenty of money to service its debt and trillions more for other expenses. The U.S. Treasury is part of the executive branch of the federal government, which is under the authority of President Biden. Thus, an actual default can only occur if Biden disregards a federal law and the Constitution. Nor would Social Security benefits be affected by a debt limit stalemate unless Biden illegally diverts Social Security revenues to other programs.
