As a result of its size, history, immigration flows, and institutional complexity at the city, county, state, and national levels, the United States is characterized by disparate yet coexisting systems of political economy and labor policy. Some of the northeastern, midwestern, and western states have at times had a kind of laborist capitalism in which public policy and prominent employers acknowledged union power and legitimacy. In the South, things are different: Mississippi and South Carolina are among the states least hospitable to unionism. In such states, local business interests have preserved low taxes, lax regulations, and low wages. The authors of Disunited States of America describe several dimensions of labor policy differentiation across the states as well as examine the underlying dynamics.
