"Why, if we don't impose any tarriffs, nobody else will!" Yeah, in your dreams, Reed.
America is the market everybody else wants into and they should pay for the privilege. America was most prosperous and funded government Constitutionally with tarriffs and excises for 100+ years and dreamers like this guy dredge up their boogeyman of Smoot-Hawley every time they want to con people into their utopian view of things. Libertarian style "free-trade" (particularly among nations) is contrary to human nature and I wish they'd just grow up and put a lid on it.
Other than that, his criticisms of the Fed & Roosevelt aren't stong enough.
You don't seem to realize that trade has two equal parties--the buyer and the seller. You can't beat up on one without giving the other a black eye as well. Let other governments beat up on their consumers, forcing artificially high prices and inflating the cost of living with high tarrifs. Free trade is almost always the economically and morally sensible policy, even if unilateral.
There, I fixed it for you.
