Much of the debate over the justice of immigration restrictions focuses on their impact on would-be migrants. Restrictionists often focus on potentially harmful effects of immigration on residents of receiving countries. This article cuts across this long-standing debate by outlining ways in which immigration restrictions inflict harm on natives, specifically by undermining their economic liberty. It covers both the libertarian “negative” view of economic freedom and the “positive” version advanced by left-liberals. Section 1 focuses on “negative” economic freedom. It shows (...) that migration restrictions massively restrict the negative economic liberty of natives. Section 2 takes up “positive” theories of economic freedom; here, too, there are massive effects. Finally, section 3 describes how to address potentially harmful side effects of migration that might undermine economic liberty. (shrink)
