Donald Trump, who leapt to the front of the Republican presidential field with his tough immigration stance, promises to deport every illegal immigrant residing in the country in less than two years, with the help of a “deportation force” — and, naturally, critics are warning of jackbooted thugs and midnight raids. There is no need for either. Much of our problem can be resolved through more modest — and less inflammatory — measures.
Estimates from the Center for Migration Studies and the Pew Research Center show that, of the 11 million illegal immigrants currently residing in the United States, approximately 2.5 million arrived after Barack Obama’s inauguration. Yet the overall number of illegal immigrants in the country has remained fairly static, meaning that illegal immigrants have been coming and going in about equal numbers. Why? Because, contrary to much political rhetoric, many illegal immigrants are not here to stay, and so are very sensitive to incentives: When the prospect of profitable work outweighs the risk of falling afoul of law enforcement, they come; when it doesn’t, they leave.
