What would happen if the U.S. military needed 1 million people in the Armed Forces but decided to cap domestic enlistment at 750,000 U.S. citizens and to recruit the rest abroad? Or what would happen if U.S. policy was designed to import 25 percent of its lawyers or teachers from elsewhere in the world, not because this country lacks people who are interested in and capable of pursuing those professions, but simply because the U.S. would rather hire foreigners for those jobs? That would be absurd—and it happens to be exactly how the system for training and hiring doctors in America operates today.
