Paul Krugman has at least three jobs: he is professor of economics and international affairs at Princeton University; Centenary Professor at the London School of Economics; and, perhaps his best-known job, an op-ed columnist for the New York Times. In recognition of his influence the Washington Monthly called him “the most important political columnist in America.”

What has gone wrong with America? With The Conscience of a Liberal, best-selling author Paul Krugman points the way to a new New Deal.

America emerged from Franklin Roosevelt's New Deal with strong democratic values and broadly shared prosperity. But for the past thirty years American politics has been dominated by a conservative movement determined to undermine the New Deal's achievements - a movement whose founding manifesto was Barry Goldwater's The Conscience of a Conservative. That movement has been highly successful in turning the clock back: both the inequality of today's America and the corruption of its political life hark back to the age of the robber barons.

Now the tide may be turning - and in The Conscience of a Liberal Paul Krugman, the world's most widely read economist and one of its most influential political commentators, charts the way to reform.

Krugman ranges over a century of history, from the political economy of the Gilded Age - which seems all too familiar these days - to the calamities of the Bush years, which he argues were inevitable once movement conservatives gained full control of the U.S. government. He shows that neither the middle-class America the baby boomers grew up in nor the increasingly oligarchic nation we have become over the past generation evolved naturally: both were created, to a large extent, by government policies guided by organized political movements. He explains how defenders of inequality have exploited cultural and racial divisions to their advantage, while reformers have found ways to bridge those divisions. And he argues that the time is ripe for another great era of reform.

Last but not least, The Conscience of a Liberal outlines a program for change. It shows how universal health care can be the centerpiece of a new New Deal, just as Social Security was the core of the original. It explains what can be done to narrow the wealth and income gap. And it shows how a new political coalition can both support and be supported by reform, making our society not just more equal but more democratic.
