Conscience of a Liberal is a book by economist and Nobel Prize-winning author Paul Krugman. In Liberal, Krugman discusses what he says is the widening gap between America's poorest and richest citizens. Krugman theorizes that the income inequality is driven by political change brought about by "radicals of the right."The New York Times: Malefactors of Megawealth (October 21, 2007)

"Political and economic reform turned the oligarchic America of the Gilded Age, a place of vast inequality, bigotry, and corruption, into the imperfect but far better society of the postwar era. The challenge now is to do again what the New Deal did: to create institutions that will support and sustain a decent society."--Paul Krugman, The Conscience of a LiberalOfficial Site: Paul Krugman
