"Paging Mr. Smoot and Mr. Hawley! Report to Congress, stat!"
You might want to study up on Smoot-Haley a bit. If I remember my history correctly, the damage of the Fed's tight money policy had already done the damage before the legislation was signed.
You talk like there were no tariffs before or after Smoot-Hawley. Of course, that's bunk. Our government used to operate on income generated from tariffs. If there were any integrity at all left in government, it still would.
