I just finished reading Chandran Kukathas’s book on immigration, Immigration and Freedom, (Princeton: 2021) and I recommend it strongly. In some respects it is a quirky book and Kukathas is coming from an intellectual home that most of the left-leaning readers of Crooked Timber are not friendly to. Hayek gets a lot of mentions, and I’m guessing that many with social democratic or Rawlsian sympathies won’t share Kukathas’s scepticism about the bounded state being a locus of political community and justice (though cf James C. Scott). Kukathas’s basic argument, though developed in detail over many pages, is that to control immigration, states need to monitor and control migrants. But in order to do this, states also need to monitor and control their own citizens. Because one thing human beings are prone to do is to associate with other human beings, independently of their immigration status. People love, befriend, work with, create with, employ others and some of those people are immigrants. So to stop immigrants from doing the things the state doesn’t want them to do, the state also has to monitor its citizens who want to do those things with them and if necessary to pass laws preventing them from doing those things.
