In Migration, Reproduction and Society, Alejandro I. Canales offers a theoretical model for understanding the dilemmas presented by migration in the transformation of contemporary society. Aging and changing demographics in advanced societies make economic and social reproduction dependent upon the contributions made by immigration. However, these same demographic processes are conducive to ethnic transformations. The political dilemma facing advanced societies is that immigration is required to ensure their reproduction, but this entails becoming multicultural societies where the political hegemony of ethnic and demographic majorities becomes radically subverted. This paves the way to a pervasive political conflict already evident in the current immigration crisis in Europe just as in the revival of racism and xenophobia in the United States.
