I don't know how many head-of-state nut cases arrived in New York for the annual meetings of the United Nations General Assembly. But surely there are many others besides Mahmoud Ahmadinejad and Muamar Gaddafi. There is a class of rulers from Africa, for example, who govern recklessly in behalf of themselves but under the cover of one or another form of millenarianism. (The brutal clowns of South America are a bit different. They still believe that Fidel Castro is a model for building the good society.) This is, I suppose, the revenge of ideology over the London School of Economics.

Long before Martin Wolf became the chief economics columnist for the Financial Times, he wrote the newspaper letters--lots and lots of letters. It was the early 1980s, the height of the Thatcher era, and Wolf was running research at a think tank in London that was sympathetic to the government's pro-trade agenda. The FT's letters section became the ideal place to take to task all those who would stand in the way of the first waves of globalization.
