Appropriately, given that it's Labor Day, one of Econlib's two feature articles is on immigration. In "Why the Conventional View of Immigration is Wrong," author and economics graduate student Daniel Kuehn challenges two conventional views on immigration:
(1) That the U.S. government should discriminate in favor of high-skill workers, and
(2) That undocumented immigration is a threat to the social fabric, domestic labor markets, and even national security.
Here's his bottom line:
The conventional view of both high-skill and undocumented immigration is misleading. The economic case for giving high-skill immigrants an advantage in the immigration process is weak. Moreover, undocumented immigrants, far from being undesirable, signal through their efforts to enter and stay in the country that they are a valuable addition to American society.
