From the article:
...Beyond deporting people who represent a genuine criminal or security threat to Americans, the rest of those targeted for deportation are people already in the workforce, at least 70 percent of whom have been living in the United States 10 years or longer, according to the Department of Homeland Security.
I asked economist Michael Clemens, a senior fellow at the Center for Global Development, about the push for additional immigration enforcement measures and even cuts in legal immigration, which appear premised on the idea that shrinking or reducing the current supply of labor would be good for the country. “There is no economic evidence that forcing millions of unauthorized workers out of the country will help the economy or help American workers,” said Clemens. “The best evidence we have, from economists Andri Chassamboulli and Giovanni Peri, suggests that forcing out those workers will actually harm U.S. workers. This is because many industries like restaurants and dairy lack any lawful channels for hiring immigrant workers.”
