Do Unskilled Immigrants Hurt the Economy?

In a City Journal article, Steven Malanga argues that unskilled immigrants harm our economy. An excerpt:

But the tale of Librado Velasquez helps show why supporters are wrong about today’s immigration, as many Americans sense and so much research has demonstrated. America does not have a vast labor shortage that requires waves of low-wage immigrants to alleviate; in fact, unemployment among unskilled workers is high—about 30 percent. Moreover, many of the unskilled, uneducated workers now journeying here labor, like Velasquez, in shrinking industries, where they force out native workers, and many others work in industries where the availability of cheap workers has led businesses to suspend investment in new technologies that would make them less labor-intensive.

Yet while these workers add little to our economy, they come at great cost, because they are not economic abstractions but human beings, with their own culture and ideas—often at odds with our own. Increasing numbers of them arrive with little education and none of the skills necessary to succeed in a modern economy. Many may wind up stuck on our lowest economic rungs, where they will rely on something that immigrants of other generations didn’t have: a vast U.S. welfare and social-services apparatus that has enormously amplified the cost of immigration. Just as welfare reform and other policies are helping to shrink America’s underclass by weaning people off such social programs, we are importing a new, foreign-born underclass. As famed free-market economist Milton Friedman puts it: “It’s just obvious that you can’t have free immigration and a welfare state.”
