The Immigration Debate We Need By George Borja. The New York Times, February 27, 2017

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.

Over the past 30 years, a large fraction of immigrants, nearly a third, were high school dropouts, so the incumbent low-skill work force formed the core group of Americans who paid the price for the influx of millions of workers. Their wages fell as much as 6 percent. Those low-skill Americans included many native-born blacks and Hispanics, as well as earlier waves of immigrants.

But somebody’s lower wage is somebody else’s higher profit. The increase in the profitability of many employers enlarged the economic pie accruing to the entire native population by about $50 billion. So, as proponents of more immigration point out, immigration can increase the aggregate wealth of Americans. But they don’t point out the trade-off involved: Workers in jobs sought by immigrants lose out.

The immigration debate will also have to address the long-term impact on American society, raising the freighted issue of immigrant assimilation. In recent decades, there has been a noticeable slowdown in the rate at which the economic status of immigrants improves over time. In the 1970s, the typical immigrant could expect a substantial improvement relative to natives over his or her lifetime. Today, the economic progress of the typical immigrant is much more stagnant.

Part of the slowdown is related to the growth of ethnic enclaves. New immigrants who find few ethnic compatriots get value from acquiring skills that allow more social and economic exchanges, such as becoming proficient in English. But new immigrants who find a large and welcoming community of their countrymen have less need to acquire those skills; they already have a large audience that values whatever they brought with them. Put bluntly, mass migration discourages assimilation.

Europe is already confronting the difficulties produced by the presence of unassimilated populations. If nothing else, the European experience shows that there is no universal law that guarantees integration even after a few generations. We, too, will need to confront the trade-off between short-term economic gains and the long-term costs of a large, unassimilated minority.

We also need some general principles, combining common sense and compassion.
First and foremost, we must reduce illegal immigration. It has had a corrosive impact, paralyzing discussion on all aspects of immigration reform. A wall along the Mexican border may signal that we are getting serious, but many undocumented immigrants enter the country legally and then overstay their visas. A national electronic system mandating that employers certify new hires, along with fines and criminal penalties for lawbreaking businesses, might go a long way toward stemming the flow.

But what about the 11-million-plus undocumented immigrants already here? A vast majority have led peaceful lives and established deep roots in our communities. Their sudden deportation would not represent the compassionate America that many of us envision. Perhaps it’s time for some benign neglect. Many will eventually qualify for visas because they have married American citizens or have native-born children. Rather than fight over a politically impossible amnesty, we could accelerate the granting of family-preference visas to that population.

We will also need to decide how many immigrants to admit. Economists seldom confess their ignorance, but we truly have no clue about what that number should be. About one million legal immigrants a year entered the country in the past two decades. The political climate suggests that many Americans view that number as too high. History shows that when voters get fed up with immigration, there is no reluctance to cut off the flow altogether. Back in the 1990s, Barbara Jordan’s immigration commission recommended an annual target of about 550,000 immigrants. Such a cut would be significant, but it may be preferable to the alternative, which, in this political climate, could mean shutting off the flow.

Finally, we need to choose between highly skilled and less-skilled applicants. High-skill immigrants, who pay higher taxes and receive fewer services and can potentially expand the frontier of knowledge, are more profitable for us. But giving an opportunity to the huddled masses is part of what makes our country exceptional.
