The first month of the Trump administration has already changed the direction of the immigration debate, with many more changes coming soon. So far, executive orders and deportations dominate the discussion. But the fight over how many refugees to admit or how best to vet those refugees obscures what the debate is really about.

Changes in social policy do not make everyone better off, and immigration policy is no exception. I am a refugee, having fled Cuba as a child in 1962. Not only do I have great sympathy for the immigrant’s desire to build a better life, I am also living proof that immigration policy can benefit some people enormously.

But I am also an economist, and am very much aware of the many trade-offs involved. Inevitably, immigration does not improve everyone’s well-being. There are winners and losers, and we will need to choose among difficult options. The improved lives of the immigrants come at a price. How much of a price are the American people willing to pay, and exactly who will pay it?

This tension permeates the debate over immigration’s effect on the labor market. Those who want more immigration claim that immigrants do jobs that native-born Americans do not want to do. But we all know that the price of gas goes down when the supply of oil goes up. The laws of supply and demand do not evaporate when we talk about the price of labor rather than the price of gas. By now, the well-documented abuses of the H-1B program, such as the Disney workers who had to train their foreign-born replacements, should have obliterated the notion that immigration does not harm competing native workers.
