Milton Friedman has been dead for more than three years. But his spirit was surely hovering protectively over Chile in the early morning hours of Saturday. Thanks largely to him, the country has endured a tragedy that elsewhere would have been an apocalypse.

It's not by chance that Chileans were living in houses of brick—and Haitians in houses of straw—when the wolf arrived to try to blow them down. In 1973, the year the proto-Chavista government of Salvador Allende was overthrown by Gen. Augusto Pinochet, Chile was an economic shambles. Inflation topped out at an annual rate of 1000%, foreign-currency reserves were totally depleted, and per capita GDP was roughly that of Peru and well below Argentina's.

What Chile did have was intellectual capital, thanks to an exchange program between its Catholic University and the economics department of the University of Chicago, then Friedman's academic home. Even before the 1973 coup, several of Chile's "Chicago Boys" had drafted a set of policy proposals which amounted to an off-the-shelf recipe for economic liberalization: sharp reductions to government spending and the money supply; privatization of state-owned companies; the elimination of obstacles to free enterprise and foreign investment, and so on.
