- The national debt’s 20-year deadline and baby boomers’ spending problem: ‘a lot of incentive for every generation to try to pass a big bill’
Economist Kent Smetters warns the U.S. federal debt is on a 20-year trajectory toward an unsustainable 210% of GDP, driven by disproportionate spending on older Americans. Retirees receive 38.6% of federal outlays, while spending per older person is 10x higher than for younger individuals, creating intergenerational fiscal challenges.
- This may be the maximum level of U.S. debt that’s sustainable before interest payments trigger a default crisis that even steep tax hikes can’t fix
The Penn Wharton Budget Model warns that U.S. debt exceeding 210% of GDP could trigger a crisis where even steep tax hikes cannot cover interest payments. Current debt is 100% of GDP, with projections reaching 175% by 2056, and healthcare cost growth could accelerate the threshold. A 15-percentage-point tax hike on labor income is proposed as a solution, but factors like higher interest rates and market instability could worsen risks.
- Trump is facing a new inflation warning from the bond market, adding to his midterm challenges
Rising interest rates linked to bond market concerns over inflation and government debt are complicating President Trump's midterm election prospects. The Iran war's energy price spike has pushed 10-year U.S. Treasury rates above 4.44%, with economists questioning Trump's deficit-reduction strategies, including tariffs and spending cuts, as unsustainable.
- Trump wants a gas tax holiday. There's a much bigger problem looming
President Donald Trump has proposed a temporary federal gas tax waiver to alleviate high gas prices, but the measure requires Congressional approval and faces debate over its effectiveness. The tax holiday could save drivers up to 18.4 cents per gallon, though critics argue it may not significantly reduce prices due to market dynamics and increased demand.
