Peter Meilaender has written one of the only single-author books on the ethics of immigration policy, and perhaps the only one that defends the position that “states are entitled, within certain wide limits, to craft immigration policies as they see fit” (p. 1). Most normative work on immigration, as he notes, supports the position that states are more ethically constrained in making immigration policy, much of it arguing for an “open borders” policy. As such, his book may serve as a useful point of reference in the debate over immigration policy.
