As longtime supporters of The Future of Freedom Foundation know, ever since our inception in 1989 we have called for open borders — genuine open borders — as the only way to resolve America's decades-old, ongoing, never-ending immigration crisis. (See our 1995 book The Case for Free Trade and Open Immigration.)

The primary reason is moral: People have the fundamental, God-given rights of freedom of travel, freedom of movement, freedom of association, liberty of contract, and economic liberty. No government, including the U.S. government, wields the legitimate authority to infringe rights that preexist government, as the U.S. Declaration of Independence points out.

The secondary reason is utilitarian: America's system of immigration controls is a socialist institution, one that is based on the core socialist principle of central planning, and has come with death, suffering, violence, and the adoption of an immigration police state in the American Southwest. 

I recently addressed the utilitarian aspect of America's system of immigration controls in three articles and in our weekly program "The Libertarian Angle":
