This book argues that modern capitalism has given way to Financialism, a new stage of political economy in which legal institutions, financial markets, and professional norms reorganize corporations, public institutions, and everyday life around the imperatives of finance. It provides the first systematic account of Financialism as the organizing order of contemporary social life. Drawing from legal history, corporate governance, and political economy, this book explains how law, financial markets, and professional practices have transformed the American corporation. It also demonstrates how these forces have extended financial discipline across labor markets, public institutions, and daily economic activity. This book traces how this transformation altered the temporal structure of economic decision-making and weakened the capacity of democratic institutions to govern society. Finally, it develops principles for post-Financialist capitalism and proposes institutional strategies to restore democratic authority. Central to this reconstruction is a theory of democratic time, a framework for reclaiming control over democratic decision-making from the accelerating demands of finance. This book is an essential reading for scholars, graduate students, and policymakers in corporate law, finance, political economy, corporate governance, and business history. It is also ideal for readers interested in how financial power reshapes democratic governance and the structure of everyday life.
