Hey, can an experienced doctor from Germany show up and start practicing in New York next week? Since the answer is no, we can say that we don't have free trade. It's not an immigration issue, if the doctor wants to work in a restaurant kitchen, she would probably get away with it. We have protectionist measures that limit the number of foreign doctors in order to keep their pay high. These protectionist measures have actually been strengthened in the last two decades.
We also have strengthened patent and copyright protections, making drugs and other affected items far more expensive. These protections are also forms of protectionism.
This is why Morning Edition seriously misled its listeners in an interview with ice cream barons Ben Cohen and Jerry Greenfield over their support of Senator Bernie Sanders. The interviewer repeatedly referred to "free trade" agreements and Sanders' opposition to them. While these deals are all called "free trade" deals to make them sound more palatable ("selective protectionism to redistribute income upward" doesn't sound very appealing), that doesn't mean they are actually about free trade. Morning Edition should not have used the term employed by promoters to push their trade agenda.
