This book brings together the most recent and the most comprehensive collection of articles on a population at risk: the children of immigrants in the United States, especially those children whose parents came to the country without legal authorization. The end of compassion and the shift to temporary migration to source the labour needs of the American economy have brought in their wake a series of consequences, some of which were predictable and others unexpected. The chapters fully document the nature and implications of the enforcement initiatives implemented by the American government in recent years and their interaction with state policies and local contexts of reception. This collection provides an exhaustive testimony of the severe conditions faced by unauthorized migrant families and their children today and their repercussions in both countries of origin and those where they currently live. The End of Compassion will be of interest to researchers and academics studying migration in the United States and ethnic and racial studies, and to advanced students of sociology, public policy, law and political science. This book was originally published as a special issue of the journal Ethnic and Racial Studies.
