From the Ming Dynasty to Ottoman Turkey to imperial Spain, the Great Powers of the world emerged as the supreme economic, political, and military forces of their time--only to collapse into rubble and memory. What is at the root of their demise, and how can the United States stop it from happening again?

A quarter century after Paul Kennedy's The Rise and Fall of the Great Powers, Glenn Hubbard and Tim Kane present a bold, sweeping account of why powerful nations and civilizations break down under the heavy burden of economic imbalance. Introducing a profound new measure of economic power, Balance traces the triumphs and mistakes of imperial Britain, the paradox of superstate California, the long collapse of Rome, and the limits of the Japanese model of growth. Most importantly, Hubbard and Kane compare the twenty-first-century United States to the empires of old and challenge Americans to address the real problems of our country's fiscal imbalance. If there is not a new economics and politics of balance, they portend that inevitable demise is ahead.

This is more than another analysis of our nation's economy; it is a groundbreaking look at the patterns of the past and a "thought-provoking analysis that has compelling relevance for America's future" (Nobel Peace Prize-winner Henry A. Kissinger).
