I employ the same principle that any rational property owner would: selectivity. A selective, libertarian immigration policy would spare a free society from being subjected to the high rates of crime, Islamic savagery, Democrat votes, and congenitally low IQs of the Third World.
Open immigration is not libertarian, and no valuer of liberty who owned a private island in a sea of hostile neighbors would proclaim a policy of unrestricted migration into his micro-nation. Globalist left-libertarians who prescribe open immigration a priori for all countries -- from Israel to Iceland -- are demanding that the people inhabiting them sacrifice their rational self-interest for a set of ideals that carry destructive consequences.
@LearnLiberty Selective immigration grows our economy w/o importing the crime, Democrat votes, and congenitally low IQs of the Third World.
