I remember being taught in high school economics

that tariffs, long a favorite tool of protectionist governments, are typically bad in the long run. You save jobs, but at a high cost, and in the end free trade is better. Of course, this being high school you never know how much you're being educated vs. fed capitalist propaganda.

So I have two questions. First, is this actually accurate, and secondly... would it make sense to think of strict immigration controls as a form of tariff on labor rather than goods?
