Book excerpt: How should Western democracies respond to the many millions of people who want to settle in their societies? Economists and human rights advocates tend to downplay the considerable cultural and demographic impact of immigration on host societies. Seeking to balance the rights of immigrants with the legitimate concerns of citizens, Strangers in Our Midst brings a bracing dose of realism to this debate. David Miller defends the right of democratic states to control their borders and decide upon the future size, shape, and cultural make-up of their populations. “A cool dissection of some of the main moral issues surrounding immigration and worth reading for its introductory chapter alone. Moreover, unlike many progressive intellectuals, Miller gives due weight to the rights and preferences of existing citizens and does not believe an immigrant has an automatic right to enter a country...Full of balanced judgments and tragic dilemmas.” —David Goodhart, Evening Standard “A lean and judicious defense of national interest...In Miller’s view, controlling immigration is one way for a country to control its public expenditures, and such control is essential to democracy.” —Kelefa Sanneh, New Yorker
