Since the advent of the European Union, politicians have increasingly emphasized the notion of a European social model as an alternative to the American form of market capitalism, which is seen as promoting economic growth without regard for solidarity and social progress. As this politicaldiscourse has advanced, social scientists and academic policy analysts have raised questions concerning the extent to which the E.U. and U.S. social models exist outside the minds of diplomats and politicians seeking to stitch together a common identity. How much unity is there still within Europeafter the Eastern enlargements have considerably increased economic and cultural diversity? To whatever extent one might discern a distinct set of commonalities that represent the core of a European approach, how different are the European characteristics of social, economic, and political life fromthose of America?Addressing these issues, this book systematically analyzes how much European countries and the United States have in common and how much variation we find within the enlarged European Union in eight central spheres of socio-economic and political life: employment, equality/mobility, educationalopportunity, integration of immigrants, democratic functioning, political participation, rights to welfare, and levels of public spending. Drawing on empirical analyses by U.S. and European scholars who represent multi-disciplinary backgrounds, each of these topics is put under scrutiny. The resultsof this study illuminate points of convergence and divergence as seen from the perspectives of scholars from both sides of the Atlantic.
