The European and U.S. socio-economic models have been interpreted traditionally as alternatives, the first based on solidarity and the second on individualism. The comparison between the social market economy outlined first by Rathenau and Roosvelt New Deal allows to capture a profound convergence between the two systems. The crisis of liberistic globalization has highlighted the need to restore a balance between public and private and has relaunched the debate on new forms of neo-liberalism. In the U.S. the New Deal is now revisited as the last major reform to continue and renew. In Europe, the Treaty of Lisbon has recognized the social market economy as the European social-economic model.
