A little protectionism might just be a good thing. We need to maintain our ability to produce steel and Al. Also, cheep prices are only good for those that have good jobs.
I'll keep saying it until the sun burns out: America flourished and grew into an industrial powerhouse under an ardently protectionist trade policy from Lincoln through Harding, and largely protectionist trade policy from Harding through Eisenhower.
Too many conservatives have swallowed the globalists' free-trade arguments because those arguments seem conservative on their face. But when you look at them a bit more carefully, they are basically arguing to allow numerous countries to continue to enjoy grossly unfair trade advantages and to force our factories and businesses to compete against foreign factories and businesses that are heavily subsidized and/or that have much lower labor and regulatory costs.
