Michael Lewis's "Boomerang" is a collection of essays that chronicle the global financial crisis of 2008. Lewis examines how the reckless lending practices of financial institutions in Iceland, Ireland, Greece, Germany, and the United States led to economic collapse. He explores the role of government intervention, the cultural factors that contributed to the crisis, and the psychological impact of these events on individuals and societies. The essays offer a unique and insightful perspective on the crisis and its consequences, highlighting the vulnerabilities of modern financial systems and the human tendency to make reckless decisions in the face of abundance.
