Political satirist and diehard libertarian P.J. O’ROURKE, author of such self-explanatory gems as Parliament of Whores: A Lone Humorist Attempts To Explain the Entire U.S. Government and Peace Kills: America’s New Fun Imperialism, winds up for a new round of economic bitch slapping in his latest, On the Wealth of Nations. Here he cuts to the concepts and makes Adam Smith’s long-winded manifesto against mercantilism seem like an accessible bit of light reading. He’ll read, sign, and make figurative love with the free market at the Coolidge Corner Theatre, 290 Harvard St, Brookline | January 29 | 6 pm | $2 | 617.566.6660.
