Summary
Citadel CEO Ken Griffin, speaking at the Citadel Securities Future of Global Markets event in New York, said that America's roughly $40 trillion national debt and recurring budget deficits cannot be resolved in Washington alone. According to Fortune, Griffin argued that U.S. allies must also grow their own economies, stating "our fiscal house is clearly not in order." The remarks follow the Treasury's confirmation of a $2 trillion deficit for fiscal year 2026, more than half of which stemmed from interest payments on the debt.

When asked for his first priority, Griffin said policymakers should "play the productivity card as hard as we can" and "grow the damn economy." He tied this to the defense debate among G7 countries, which President Trump has pressed since returning to office. Griffin called the U.S. tariff war with Europe a "fiasco" and said allies should use the moment to take on more of their own defense costs. He cited French labor rules limiting work to 48 hours per week, or 44 hours on average over 12 weeks, and the custom of extended summer holidays.

Fortune noted that Griffin's hours-based argument is simplistic. Citing Our World in Data, it reported that Norway's 2023 GDP per capita was close to $99,000 with about 1,412 annual hours worked, while the U.S. had GDP per capita of just under $73,000 with about 1,789 hours per worker. The U.S. spends approximately 3.1% to 3.4% of GDP on defense, while France's military budget, per Politico, will rise to €63.4 billion ($71 billion) in 2027, roughly 2% of its GDP.

Griffin also outlined broader measures, including building data centers in America and increasing focus on nuclear fusion and robotics, which he said would unlock productivity for the next two decades. He added that education reform and immigration policy are essential, saying he wants "every single brilliant person around the world" to live in America. He framed the challenge as a shared Western one, saying "we're going to get out of these waters by making the pie bigger for all of us."
