Here's a smell test. Pretend you're a man from Mars knowing absolutely nothing about Earth and you're looking for a nice place to land. You find out that there's one country, say, country A, where earthlings from other countries voluntarily invest and entrust trillions of dollars of their hard earnings. There are other countries where they're not nearly as willing to make the same investment. Which one of those countries would you deem the most prosperous and with the greatest growth prospects? You'd pick country A, which turns out to be the United States. As such, you'd be just like most of the world's population who, if free to do so, would invest and live in the U.S.
The late Professor Milton Friedman said, "Underlying most arguments against the free market is a lack of belief in freedom itself." Some people justify their calls for protectionism by claiming that they're for free trade but fair trade. That's nonsense. Think about it: When I purchased my Lexus from a Japanese producer, through an intermediary, I received what I wanted. The Japanese producer received what he wanted. In my book, that's a fair trade.
Of course, an American auto producer, from whom I didn't purchase my car, might whine that it was unfair. He would like Congress to impose import tariffs and quotas to make Japanese-produced cars less attractive and available in the hopes that I'd buy an American-produced car. In my book, that would be unfair.
