To grasp American immigration policy, to the extent that it can be grasped, one need only remember that the United States forbids smoking while subsidizing tobacco growers.

It’s a story I’ve heard many times—from a landscaper, a construction firm, a junkyard owner, a group of plant nurserymen, and so on. “We need Mexicans.” You could yell “Migra!” in a lot of restaurants in Washington, and the entire staff would disappear out the back door. Do we expect businessmen to vote themselves out of business? That’s why we don’t take the obvious steps to control immigration (a thousand-dollar-a-day fine for hiring illegals, half to go anonymously to whoever informed on the employer).
