Obviously, the big political news of the past couple of days has come from the Democratic side. But before last week’s Republican National Convention fades from view, let me focus instead on a development on the GOP side that may, given everything else that has been happening, have flown under the radar: MAGA rhetoric on immigration, which was already ugly, has become even uglier.

Until now, most of the anti-immigration sloganeering coming from Donald Trump and his campaign has involved false claims that we’re experiencing a migrant crime wave.

Increasingly, however, Trump and his associates have started making the case that immigrants are stealing American jobs — specifically, the accusation that immigrants are inflicting terrible damage on the livelihoods of Black workers.

Of course, the idea that immigrants are taking jobs away from native-born Americans, including native-born Black Americans, isn’t new. It has, in particular, been an obsession for JD Vance, complete with misleading statistical analysis, so Trump’s choice of Vance as his running mate in itself signals a new focus on the supposed economic harm inflicted by immigrants.

So, too, did Trump’s acceptance speech on Thursday, which contained a number of assertions about the economics of immigration, among them, the notion that of jobs created under President Joe Biden, “107 percent of those jobs are taken by illegal aliens” — a weirdly specific number considering that it’s clearly false, because native-born employment has risen by millions of jobs since Biden took office.

What seems relatively new, however, is the attempt to pit immigrants against Black Americans. True, Trump prefigured this line of attack during his June debate with Biden, when he declared that immigrants are “taking Black jobs,” leading some to mockingly question which jobs, exactly, count as “Black.”
But the volume on this claim has been turned way up.

At the Republican convention, former Trump adviser Peter Navarro, someone very likely to have a role in the next administration if Trump wins, spoke of “a whole army of illiterate illegal aliens stealing the jobs of Black, brown and blue-collar Americans.”

In an interview with Bloomberg Businessweek published last week, Trump went even bigger, declaring that “The Black people are going to be decimated by the millions of people that are coming into the country.” He continued, “Their wages have gone way down. Their jobs are being taken by the migrants coming in illegally into the country.” He went on to say, “The Black population in this country is going to die because of what’s happened, what’s going to happen to their jobs — their jobs, their housing, everything.”

Trump’s diatribe forced Bloomberg to add this, parenthetically, as a fact check: “According to the U.S. Bureau of Labor Statistics, the majority of employment gains since 2018 have been for naturalized U.S. citizens and legal residents — not migrants.”

There was a time when a rant like this would have signaled that a politician lacked the emotional stability and intellectual capacity to hold the highest office in the land. Alas.

Also, it’s hard to overstate the cynicism here. Trump has a history of associating with white supremacists, not to mention his long-standing obsession with crime in urban, often predominantly Black precincts. Still, he clearly perceives an opportunity to peel away some Black voters by playing them off against immigrants.

But again, even if we ignore the cynicism, this new line of attack on immigration is just wrong on the facts.
If immigrants are taking away all the “Black jobs,” you can’t see it in the data, which shows Black unemployment at historic lows. If Black wages have, as Trump claims, gone way down, someone should tell the Bureau of Labor Statistics, which says that median Black earnings, adjusted for inflation, are significantly higher than they were toward the end of Trump’s term. (You should ignore the spurious bump during the pandemic, which reflected composition effects rather than genuine wage gains.)
You might ask why, given we have indeed seen a surge in immigration, that we aren’t seeing signs of an adverse, let alone cataclysmic, impact on Black wages or employment. After all, many recent immigrants, especially those in the country without legal permission, lack college degrees and maybe even high school education. So aren’t they competing with native-born Americans who also lack college or high school degrees?

The answer, which we’ve known since the 1990s, is that immigrant workers bring a different set of skills to the table than native-born workers, even when those workers have similar levels of formal education. And yes, I mean skills: If you think of workers without a college degree as “unskilled,” try fixing your own plumbing or doing your own carpentry. It shouldn’t need to be said, but a lot of blue-collar work is highly skilled and highly specialized. As a result, immigrants tend to take a very different mix of jobs than native-born workers do — which means that there’s much less head-to-head competition between immigrant and native-born workers than you might think, or what Trump and Vance want you to think.

The bottom line is that the attempt to portray immigration as an apocalyptic threat to Black Americans is refuted by the facts. Will it nonetheless work politically? I have no idea.
