Good Post.
Funny, I never heard about Hoot Smalley "causing" the great depresssion until the 1980's when the "no borders/no trade barriers" fanatics started to crank out their propaganda. Given the small percentage of US GNP that was involved in foreign trade in the 1930s it wasn't important.
I'd like someone to tell me how foriegn trade increased from 1938 to 1948. I don't think it was a lot, even though we were still in the depression in 1938, and out of it in 1948.
If trade barriers started depressions, why did Japan become rich? They have never believed in "free trade".
Why did trade increase after 1938? Here's a good reason. By this time, Secretary of State Cordell Hull had finally persuaded FDR to abandon Smoot-Hawley and replace it with the pro-free trade policy of making Most Favored Nation Treaties.
Most of the rest of the industrialized world was in ruins, for one thing. I'm guessing that they had to buy stuff from
the US, with "loans" from US taxpayers, that is.
