This is the first time since World War II that debt has been so high a percentage of national economic output. > That is a big problem because the federal debt undermines the value of the U.S. dollar and diverts investment from the wealth-creating private sector. The rising debt and its pressure on the nation’s economy will force the federal government and Federal Reserve, the latter led by newly confirmed chair Kevin Warsh, to make hard decisions they have put off for decades. > Many among the public will suffer as a result, especially the elderly, who rely on Social Security and Medicare. > GDP is the total amount of spending in the nation’s economy. At the end of March, federal debt held by the public was $31.265 trillion, and GDP in 2025 was $31.216 trillion.
