Elon Musk backed Warren Buffett’s deficit-cutting idea in June, posting “This is the way” on X as he shared the investor’s old warning that the federal deficit could be wiped out in five minutes. The nod revived a proposal Buffett first made in a 2011 CNBC interview, when he said he could end the deficit if lawmakers faced a hard political penalty for overspending.
Buffett’s plan would make all sitting members of Congress ineligible for reelection if the deficit exceeded 3% of GDP. Musk’s post came as the national debt hit $38.9 trillion, or 124% of the economy, according to the U.S. Treasury, and heads toward $40 trillion if it keeps rising at its current pace.
The debt load is not just a headline number. Last year, it rose by $2.6 trillion, public liabilities moved above the size of the economy for the first time since World War II, and interest on the national debt now costs more than $22 billion a week, according to the Congressional Budget Office. On March 9, the Committee for a Responsible Federal Budget warned that the average interest rate on the national debt could exceed economic growth by fiscal year 2031, a point that would make deficits harder to contain even if Washington tries.
That is why Buffett’s old idea has resurfaced in a new political moment. In January, a bipartisan group of representatives introduced a resolution aimed at lowering the deficit to 3% of GDP, echoing the same threshold Buffett set more than a decade ago. He repeated the theme at Berkshire Hathaway’s shareholders meeting in May 2024, saying higher taxes for businesses may be coming and that U.S. debt would be acceptable for a very long time because there is not much alternative.
The friction is obvious: lawmakers can endorse a target, but they have not shown any appetite for a rule that would threaten their own jobs. Buffett’s proposal was meant to change incentives by tying fiscal discipline to reelection, not to another round of speeches about restraint. Musk’s endorsement did not create that debate, but it gave it fresh reach at a moment when the country is already looking at a debt path that points to $40 trillion.
For now, the question is not whether Buffett’s five-minute fix is elegant. It is whether Washington is willing to touch the incentives that keep the deficit growing while the bill for borrowing keeps climbing.
