Stein's Law, named after Reagan-era economist Herbert Stein, states: if something cannot go on forever, it will stop — applied here to US debt and political dysfunction.

Bartlett produces a graph showing US national debt growth from 1970 to 2026 as a rocket launch trajectory, and connects it to Ray Dalio's 80-year great power cycle theory, which he discussed with Dalio just days earlier. Buttigieg reaches for Stein's Law — named after Herbert Stein, the Reagan-era economist and father of Ben Stein of Ferris Bueller fame — to make the simple but powerful point that what cannot go on forever will stop. He cites analysis suggesting that if you start the clock at the 2001 Bush tax cuts and add the Trump cuts, those two decisions alone fully account for the debt increase; without them, the debt would be falling. The only question is whether the stopping happens through deliberate reform or through catastrophe — and that, he says, is the entire reason he is in public life.

Stein's Law says: if something can't go on forever, it won't. The US debt trajectory, the political dysfunction, the inequality — all of it must eventually end. Pete Buttigieg believes there are only two outcomes: reform or catastrophe, and that is why he is in public life.
