The book offers a bold and provocative interpretation of the American federation: the United States simultaneously restrains and liberates its constituent parts. Rhetorically the union promises unity and equality, but in practice federal institutions, economic mechanisms, and political norms impose constraints that sometimes act like a prison for individual states. At the same time different states become fields for experimentation and opportunities to implement alternative models of development — social, economic, and legal. The study combines legal analysis, economic data, and vivid state case studies with contrasting trajectories to show how centralization of power, preemption, interstate competition, and internal inequalities shape real freedom and possibilities. The book is intended for specialists and a broad audience interested in politics, law, and socioeconomics.
