My South American trip is in full swing and, again and again, I've been struck by the way that Chile and Brazil, the two countries I'm visiting, have, on key issues, transcended the tired division between left and right the United States seems hopelessly mired in. Chile is led by a president from the right, Brazil by a president from the left. But both have gone beyond stereotypes and shibboleths in order to tackle hard problems. My first stop was Santiago, Chile, where I interviewed President Sebastián Piñera. Piñera is the third richest man in Chile; a former professor with a Ph.D. from Harvard; and the first right-wing president Chileans have elected in the two decades since Pinochet. So it's surprising to learn that his signature goal is the elimination of poverty. "By the end of the decade," he tells me, "we want to have closed the gap in income between rich and poor."
