Free migration
Free migration or open immigration is the position that people should be able to migrate to whatever country they choose, free of monetary charge. Although the two are not the same issue, free migration is similar in spirit to the concept of free trade, and both are advocated by free market economists on the grounds that economics is not a zero-sum game and that free markets are, in their opinion, the best way to create a fairer and balanced economic system, thereby increasing the overall economic benefits to all concerned parties. Notwithstanding noteworthy differences among these political ideologies, many libertarians, liberals, socialists, and anarchists advocate open immigration, as do Objectivists. From a human-rights perspective, free migration may be seen to complement Article 13 of the Universal Declaration on Human Rights:
Everyone has the right to freedom of movement and residence within the borders of each state.
Everyone has the right to leave any country, including his own, and to return to his country.
