In 2024, there were more than 300 million migrants across the world—double the number there were in 1990. Many of those had been displaced by conflict or climate change; many were simply looking for jobs and a better life. But the national and multilateral systems designed to manage these flows have proved grossly inadequate, helping set off political convulsions not just in the United States and Europe but in countries around the world, including in Africa, Latin America, and South Asia. In democracies, migration has perhaps become today’s most fraught and divisive political issue.

To Amy Pope, the director general of the International Organization for Migration, these “unprecedented levels” of migration and the crackdowns that have come in reaction make abundantly clear that the current global immigration system is failing. It is, she wrote in Foreign Affairs last year, “incapable of contending with today’s humanitarian needs, demographic trends, or labor-market demands.” 

Pope argues that a challenge of this scale demands a complete system overhaul—a rebuilding of global migration policy that prioritizes order and dignity. Without such a restructuring, Pope warns, the risks of “more social unrest, more inequality,” and, ultimately, “more abuse and exploitation” of the world’s most vulnerable people will only grow.
