Democrats are in denial on immigration

Those who are members of this community are known as American citizens. They get a say in what laws get passed and how they get enforced. Those who are not members of this community — who are not citizens — don’t get such a say. The community is perfectly within its rights to decide which and how many of these outsiders will be allowed to visit the country, how long they will be allowed to stay, when they will need to go, and how many, if any, will be permitted to join the community permanently by becoming citizens.

This is one of the most elemental acts of politics: the community deciding who to admit and on what terms. To treat this act as somehow morally illegitimate is to treat politics as such as morally illegitimate.

Note that nothing I’ve said tells us anything about how many immigrants or refugees the political community of the United States should welcome at any given moment of history, or what criteria should be used to make this determination. I generally favor liberal immigration policies; many Trump voters take a very different view. The point, as Josh Barro recently argued in an important column, is that the policy debate needs to be made in terms of the good of the political community as a whole and in its parts, not in terms of abstract, extra-political moral duties owned to prospective newcomers. A political community exists in large part to benefit itself — to advance the common good of its citizens. There’s nothing shameful in that. It’s to a considerable extent what politics is.
