Imagine you were planning a conspiracy to limit the number of doctors in America. Certainly, you’d make sure to have a costly, lengthy credentialing system. You would also tell politicians that America has too many doctors already. That way, you could purposefully constrain the number of medical-school students. You might freeze or slash funding for residencies and medical scholarships. You’d fight proposals to allow nurses to do the work of physicians. And because none of this would stop foreign-trained doctors from slipping into the country and committing the crime of helping sick people get better, you’d throw in some rules that made it onerous for immigrant doctors, especially from neighboring countries Mexico and Canada, to do their job.
Okay, I think you’ve caught on by this point. America has already done all of this. Starting in the late 20th century, medical groups asserted that America had an oversupply of physicians. In response, medical schools restricted class sizes. From 1980 to 2005, the U.S. added 60 million people, but the number of medical-school matriculants basically flatlined. Seventeen years later, we are still digging out from under that moratorium.
