"Europe is at a crossroads. Demography, labor market realities, and already overwhelmed social protection systems mean that immigration will play a larger role in Europe in the decades ahead. The policy challenge is this: How can the European Union absorb new flows of immigrants when the 35 to 40 million foreign-born people already in its midst continue to face difficulties in becoming a full part of the economic, cultural, social, and political lives of their adopted societies?."--BOOK JACKET
