On December 10, 2023, Argentina embarked on a journey into the unknown. Its new leader, Javier Milei, was an anarcho-capitalist economist with the untamed hair of a rock star and a penchant for brandishing a roaring chainsaw at his rallies. For a nation crushed by hyperinflation and decades of decline, he was either a madman or a messiah. Promising a brutal "shock therapy" to cure a century of economic ills, Milei turned his back on the political establishment and declared war on the "caste," vowing to demolish a state he views as a criminal enterprise. This book is the definitive biography of the man who became a global phenomenon. Delve into the making of a rebel, tracing Milei's path from a solitary goalkeeper and frontman for a Rolling Stones cover band to a fervent disciple of Austrian economics. Discover how a fiery television pundit, known as "El Loco" for his explosive tirades, harnessed the power of media and online outrage to build a political movement from scratch. The narrative follows his improbable rise, from a stunning congressional victory in 2021 to his conquest of the presidency in 2023, a result that sent shockwaves across the world. At the heart of the story is his unbreakable bond with his sister Karina, the enigmatic figure he calls "The Boss" and the true architect of his revolutionary ascent. Once in power, the revolution began. This account provides a detailed, inside look at the first tumultuous year of the Milei presidency. Witness the implementation of the "Chainsaw Plan," a relentless campaign of slashing state spending, and the "blender" of inflation used to achieve a historic budget surplus. Explore the fierce confrontations with Argentina's powerful unions, the massive street protests from students and social movements, and the government's grueling battles with Congress to pass its radical reforms. From the audacious plan to dollarize the economy to a complete realignment of foreign policy toward the United States and Israel, the book chronicles an administration's attempt to remake a nation. Beyond the headlines and the economic data, this biography deconstructs the man and the myth. It explores the profound contradictions of a figure who is both a serious academic and a master showman, an avowed anarchist who now commands a state. Uncover the unconventional inner world that guides him, from his deep spiritual beliefs to his unique relationship with his five cloned mastiffs, whom he considers his most trusted strategists. This is a story of personal trauma, intellectual conviction, and an almost mystical self-belief that has reshaped a country. Is Javier Milei a visionary leader undertaking a painful but necessary reconstruction, or a dangerous demagogue leading his country toward ruin? This book provides an unvarnished and comprehensive look at the forces that propelled him to power, the realities of his governance, and the high-stakes future he is forging for Argentina. It is an essential account of one of the most audacious and consequential political experiments of the 21st century.
