The End of the Myth

"Ever since this nation's founding, the idea of an open and ever-expanding frontier has been central to American identity. Symbolizing a future of endless promise, the frontier made possible the United States' belief in itself as an exceptional nation--democratic, individualistic, forward-looking. Today, though, the country has a new symbol: the border wall. In [this book], acclaimed historian Greg Grandin explores the effect that constant, relentless expansion had on America's domestic politics, examining the full sweep of U.S. history--from the American Revolution to the Spanish-American War, the New Deal to the election of 2016. For centuries, he shows, the ability to move outward--fighting wars and opening markets--provided America with a "gate of escape," helping to deflect domestic political and economic conflicts. But this deflection meant that the country's problems, from racism to inequality, were never confronted directly. And now, the combined catastrophes of the 2008 financial meltdown, our unwinnable wars in the Middle East, and a deepening ecological crisis have slammed this gate shut, bringing political passions that had long been directed elsewhere back home.
