Book excerpt: The Decline of America offers a carefully documented analysis of the last seventeen U.S. presidents. These men, eight Democrats and nine Republicans, have shaped the last 100 years, not only for America, but for the world. Each president is profiled with unsparing scrutiny so we can see where it’s all gone wrong. David Schein follows these critiques by proposing ways to improve America’s outlook for the next 100 years—before it’s too late.
