Why has immigration become so politically divisive – and why is it so difficult for governments to design policies that satisfy both public concerns and economic needs?

In this episode, MPI’s Meghan Benton speaks with Madeleine Sumption, Director of the Migration Observatory at the University of Oxford and a member of the UK's Migration Advisory Committee. Drawing on insights from her new book, What Is Immigration Policy For?, she explains why immigration policy involves trade-offs between economic, humanitarian, and political goals—and why these tensions often lead to public dissatisfaction. The episode also examines challenges in regulating unauthorized migration and spontaneous asylum flows, the limits of deterrence policies, and decisions around low-wage labor migration.
