Throughout the developed world, we’ve seen a resurgence in recent years of anti-immigrant, nationalist politics. Donald “build a wall and make Mexico pay for it” Trump is still leading in national republican polls in the United States. In Europe, parties like UKIP, Front Nationale, and Golden Dawn have increased support and in some cases pushed mainstream conservatives parties into adopting stricter immigration controls. In Japan, the government continues to oppose immigration despite a population that is rapidly aging. In Australia, refugees are effectively detained in concentration camps. This is happening despite an increasingly strong research consensus that shows that working age immigrants contribute to economic growth, strengthen national pension systems, reduce government deficits, and commit crimes at a lower rate than the rest of the population. Those of us who acknowledge that research often feel that there is something xenophobic, even deeply sinister about anti-immigration politics. But when we point this out, we are often unable to satisfactorily defend the point–there seems to be an immense gap between the relatively modest claim that we ought to improve border security and outright fascism. But despite this difficulty, the connection does exist–anti-immigration politics and fascism are deeply interrelated, and I intend to prove it to you as best I can.
