Freedom of migration is one of the widely accepted and wholly admirable principles of liberalism. But should this generally give the stranger a right to settle down in a community in which he is not welcome? Has he a claim to be given a job or be sold a house if no resident is willing to do so? He clearly should be entitled to accept a job or buy a house if offered to him. But have the individual inhabitants a duty to offer either to him? Or ought it to be an offence if they voluntarily agree not to do so? Swiss and Tyrolese villages have a way of keeping out strangers which neither infringe nor rely on any law. Is this anti-liberal or morally justified? For established old communities I have no certain answers to these questions.
