The Liberal case for controlled Immigration

This article on US immigration probably isn't everyone's cup of tea, but I thought it was interesting to hear the Libertarian case against unlimited immigration. It's a thought provoking piece and makes a powerful arguement that open borders actually threaten the freedoms of a Liberal society.

The Fallacy of Open Immigration

'To the degree that a nation is like a house, and requires the security of a house, its inhabitants must have the ability to decide whom they wish to invite inside, whom they wish to enjoy the many investments already made in it. If the house is designed to protect individual liberty, its maintenance requires the exclusion of people whose ill-advised decisions might endanger liberty's protective mechanisms.'

No one has the right to move to a free country and destroy its freedom. But this is precisely what happens when people who are unused to the political culture of individual liberty, or who disapprove of it, swing the balance of national decisions.

Many libertarians imagine that all economic and political problems will be solved if only the proper economic and political framework is established: free enterprise, limited government, clear recognition of individual rights. But the question is, How can such a framework, such a "house," be preserved? It can't be preserved if people must continually be convinced, by the tens of millions, that liberty is a good idea, better than the welfare state or some structure of political repression and intolerance. It can be preserved only by a culture in which the vast majority of people assume that individual liberty and responsibility are the ultimate political good. Not every culture makes these assumptions.

There is no foreign army occupying Mexico, Canada, or Saudi Arabia. The political systems, the political errors, of these countries are the result of their own political cultures, just as America's political errors result from its own political culture. An essentially libertarian political system must be supported by essentially libertarian cultural assumptions, by a culture in which virtually no one sees a cartoon satirizing a religious figure and immediately concludes, "Somebody should be punished for this."'
