An entertaining and deeply insightful history of a decade that matters more than we think: the 1990s. Nearly a quarter century after the decade of the 1990s ended, what really mattered in America during that era is finally coming into focus. Many of the most important developments in politics, culture, and society today have roots in that era: the rise of right-wing extremism, broad transformations in voting preferences among both the working and professional classes; the spread of neoliberal economic policy; and the rise of social media. In Why the Nineties Matter, Terry Anderson provides a broad-ranging history of America in that decade. Not simply a chronological account, the book focuses on key trends that either began or gained steam then and which have had lasting effects until this day. Threading together politics, economic transformations, and socio-cultural trends, he focuses on what mattered most in retrospect. Violent and extremist white nationalism intensified greatly in that decade, evidenced by the Oklahoma City bombing and the rise of the militia movement. The defection of the white working class from the Democratic Party began then as the Democrats expanded free trade and tried to cultivate professional-class Americans. Racial and gender politics transformed, birthing new movements that would grow in influence in the next century. Social media first emerged in the 1990s too, and its impact on all aspects of life cannot be underestimated. In foreign policy, America's long wars in the Middle East and Afghanistan have roots in US policies in the 1990s. And the current standoff between the US and Russia traces back to disagreements over NATO expansion a quarter century ago. A pithy and highly readable interpretive history of a decade that matters more than most think, this book will be an essential guide to anyone trying to understand that era.
