In this interview, we discuss Kukathas's book, Immigration and Freedom, in which he argues that while immigration is often seen as a danger to Western liberal democracies because it threatens to undermine their fundamental values, most notably freedom and national self-determination, the greater threat comes not from immigration but from immigration control. We also discuss the legitimate concerns that some citizens have about immigrants receiving governmental assistance, the lowering of wages, the change in culture, assimilation, and the role of xenophobia in anti-immigrant sentiments.
