Today’s bitter divides focus too narrowly on enforcement. All sides need to be clearer about what immigration policy is meant to achieve
The immigration debate in the U.S. has been contentious for decades, but Donald Trump’s candidacy and election have taken it to a new level of polarized animosity. Politicians and the public have focused, understandably, on Mr. Trump’s promise to build a “big, beautiful” wall on the U.S.-Mexico border and on what should be done with the millions of illegal immigrants currently in the country.
These are certainly important issues. But they are enforcement issues. They are less fundamental than a question that too often goes unaddressed in our debates: Why limit immigration at all? Almost everyone at least pays lip service to the need for limits of some kind, but we don’t often enough challenge each other to explain what limits we support and why.
If we are ever to have a rational debate about immigration—rather than a screaming match among combatants mostly intent on signaling their own moral virtue or ideological purity—the starting point has to be a candid acknowledgment of our goals and preferences. Politicians and ordinary voters shouldn’t be allowed to get away with saying “Of course there should be limits on immigration, but…” without explaining what they mean.
Almost all of the arguments for limiting immigration share a common theme: protection. Even those advocating much more liberal immigration policies acknowledge the need to protect Americans from terrorists, foreign criminals and people who pose a threat to public health. Supporters of stricter limits, such as me, seek wider protections: protection for less-skilled workers, protection for the social safety net, and protection for the civic and cultural foundations of American society.
