Modern life places a special emphasis on private affairs. Social institutions, and especially our economies, have been organized to facilitate the pursuit of private interests. At the center of this private world is a system of private property which, more than anything, satisfies our wants. Political economy studies the properties of this private world: How does it work, and how well does it satisfy our wants? What are the limits of the world of private affairs? Wealth and Freedom provides an introduction to political economy for the student or other interested nonspecialist. The book explores such key issues as the place of our economy in the larger social system, the importance of market institutions for individual autonomy, private enterprise as a system of economic development, poverty and inequality in market economies, global inequality, and the limits of the market and the role of government. Wealth and Freedom is distinctive in employing a rights-based approach to understanding and evaluating economic institutions. The author emphasizes the distinction between needs and wants as the basis for establishing the limits of the market, and concludes the book with a discussion of the relation between private wants and public ends.
