Protectionism Is a Boomerang That Whacks Its Proponents

As a Canadian, I have to admit that President Trump is right when he criticizes a new Canadian policy that gives Canada's producers an incentive to buy domestic supplies of ultra-filtered milk. But the biggest victims of Canadian supply management policies aren't American dairy farmers, they are Canadian consumers. Ironically, President Trump uttered his criticism as his office was releasing a memo setting the stage for tariffs on steel imports. Who would be the biggest victims of that? American consumers, and American workers in industries that use steel.
