That is what this nation said in 1928 and the result was the Smoot Hawley tariff to limit the importation of cheap foreign goods. There was a real rejection of illegal immigration. Italian immigrants were called WOPS because they were undocumented workers. WOPS is an acronym or With Out Papers. The result of the Smoot Hawley tariff and severely limited immigration was the implementation of retaliatory tariffs all over the world. The result of that was the great world wide depression.
A depression.. you mean going back to the model that made us a wealthy nation prior to free trade will lead us to a depression. I think you'll need to establish that factually.
Your Smoot Hawley reference is sheer moronic nonsense. Nobody is recommending any such thing. Just another strawman from the treason playbook to color the argument with utter nonsense.
Right on cue, the big lie. How very boring.
