I Love Capitalism!: An American Story is a 2018 memoir by Ken Langone, co-founder of The Home Depot and a prominent American investor and philanthropist. The book chronicles Langone's journey from humble beginnings in Roslyn Harbor, Long Island, as the son of a plumber and a cafeteria worker, to becoming one of the most successful businessmen in the United States. It details his entrepreneurial ventures, including his role in taking the New York Stock Exchange public and his investments in various companies, while emphasizing themes of hard work, grit, opportunity, and the virtues of capitalism. Published by Portfolio (an imprint of Penguin Random House), the memoir became a New York Times bestseller and has been praised for its candid, iconoclastic tone and passionate defense of free-market principles. Langone uses the book to argue against what he sees as misguided economic policies, critique regulatory overreach, and celebrate individual achievement and the American Dream. The memoir also touches on his philanthropy, including his support for education and healthcare initiatives, and reflects his broader influence in finance and politics. Through personal anecdotes, it serves as both a motivational story and a commentary on American capitalism, drawing from Langone's experiences to inspire readers about the potential for success through determination and market-driven opportunities.
