When I was growing up in the 1980s, I watched my grandfather — my dad’s stepdad — struggle with his own prejudice. He was a blue-collar World War II veteran who loved his family above all things and was constantly afraid for them. He carried a gun and, like many men of his generation, saw threats in people he didn’t understand: African-Americans, independent women, gays. By the time he died, 10 years ago, he had softened. He stopped using racist and homophobic slurs; he even hugged my gay cousin. But there was one view he wasn’t going to change. He had no time for Hispanics, he told us, and he wasn’t backing down. After all, this wasn’t a matter of bigotry. It was plain economics. These immigrants were stealing jobs from “Americans.”

I’ve been thinking about my grandfather lately, because there are signs that 2015 could bring about the beginning of a truce — or at least a reconfiguration — in the politics of immigration. Several of the potential Republican presidential candidates, most notably Jeb Bush, have expressed pro-immigration views. Even self-identified Tea Party Republicans respond three to two in favor of a path to citizenship for undocumented immigrants. Every other group — Republicans in general, independents and especially Democrats — is largely pro-immigrant. According to Pew, roughly as many people (18 percent of Americans) believed in 2010 that President Obama was a Muslim as believe today that undocumented immigrants should be expelled from the United States. Of course, that 18 percent can make a lot of noise. But for everyone else, immigration seems to be going the way of same-sex marriage, marijuana and the mohawk — it’s something that a handful of people freak out about but that the rest of us have long since come to accept.

Scratch the surface, though, and you’ll pretty quickly find that many Americans are closer to my grandfather’s way of seeing things than they might find comfortable acknowledging. I am referring not to the racial animus but to the faulty economic logic. We generally support immigration when the immigrants are different from us. People in the middle and upper-middle classes don’t mind poorly educated, low-skilled immigrants entering the country. Nor do we mind highly educated professionals coming in — unless, that is, we are in the same profession ourselves. More broadly, those of us advocating an immigration overhaul are basically calling for official recognition of the status quo, through offering legal status to some of the roughly 11.2 million undocumented workers who aren’t going away. Few of us are calling for the thing that basic economic analysis shows would benefit nearly all of us: radically open borders.

And yet the economic benefits of immigration may be the ­most ­settled fact in economics. A recent University of Chicago poll of leading economists could not find a single one who rejected the proposition. (There is one notable economist who wasn’t polled: George Borjas of Harvard, who believes that his fellow economists underestimate the cost of immigration for low-­skilled natives. Borjas’s work is often misused by anti-immigration activists, in much the same way a complicated climate-­science result is often invoked as “proof” that global warming is a myth.) Rationally speaking, we should take in far more immigrants than we currently do.
