Trumpist protectionists would have no one to blame but themselves.
Unfortunately, the rest of us would have to suffer through it, too.
The Smoot-Hawley tariffs of the 1930s reduced US imports and exports by 65%.
I think perhaps those tariffs in the early part of the 20th Century were a lot different than they would be today.
Now, other countries are imposing all sorts of tariffs on us, but we do not try to balance with our own. To balance is wisdom. To just try to make more money for a bankrupt country on the backs of other countries is destructive.
