is the first comprehensive history of these federal entitlement programs. Combining economics, history, political science, and law, John F. Cogan reveals how the creation of entitlements brings forth a steady march of liberalizing forces that cause entitlement programs to expand. This process—as visible in the eighteenth and nineteenth centuries as in the present day—is repeated until benefits are extended to nearly all who could be considered eligible, and in turn establishes a new base for future expansions. His work provides a unifying explanation for the evolutionary path that nearly all federal entitlement programs have followed over the past two hundred years, tracing both their shared past and the financial risks they pose for future generations.
