I like your idea.
Except why can’t we do both. :D
(I know, I saw your /s)
I think we could do both. We wouldn’t have to actually send illegals back to Mexico or anywhere else. We could send a busload from Chicago to Denver. A different busload from Denver to Miami. Miami to Green Bay, etc., etc., and around and around we go. Think a land based “Con Air”. Fund it with the increased tariffs from China, Mexico, et al.
