14. Immigration and the Political Community

This chapter argues against policies that restrict immigration. It contends that states should have open borders that allow an individual to move between political communities. The chapter begins by defending a presumption in favour of open borders that appeals to the value of freedom of movement. It then responds to those who deny that freedom of movement is sufficiently important to generate such a presumption, as well as to those who insist that states enjoy a prerogative over whether or not to grant an individual the opportunity to migrate. The chapter considers a range of objections that emphasize how open borders can jeopardize the security, economy, and culture of receiving states, showing that a proper concern for these values is consistent with borders that are largely (even if not fully) open.
