Description
A Greek letter is buried in the models that govern your life. It decides your mortgage, your pension, your country’s credit rating, and how much tomorrow’s climate damage is worth today. Called delta, it measures how fast capital destroys itself. Every model treats it as a constant. It isn’t: it has been rising for half a century across the twenty largest economies. When it moves, the equilibrium those models promised ceases to exist. It doesn’t shift. It vanishes.
