In Transaction Man, Nicholas Lemann explains the United States<U+2019><U+2015>and the world<U+2019>s<U+2015>great transformation by examining three remarkable individuals who epitomized and helped create their eras. Adolf Berle, Franklin Delano Roosevelt<U+2019>s chief theorist of the economy, imagined a society dominated by large corporations, which a newly powerful federal government had forced to become benign and stable institutions, contributing to the public good by offering stable employment and generous pensions. By the 1970s, the corporations<U+2019> large stockholders grew restive under this regime, and their chief theoretician, Harvard Business School<U+2019>s Michael Jensen, insisted that firms should maximize shareholder value, whatever the consequences. Today, Silicon Valley titans such as the LinkedIn cofounder and venture capitalist Reid Hoffman hope “networks” can reknit our social fabric. Lemann interweaves these fresh and vivid profiles with a history of the Morgan Stanley investment bank from the 1930s through the financial crisis of 2008, while also tracking the rise and fall of a working-class Chicago neighborhood and the family-run car dealerships at its heart. Incisive and sweeping, Transaction Man is the definitive account of the reengineering of America and the enormous impact it has had on us all.
