And another thing, It doesn't matter one bit what you argue here or how revolting your ideas are, the Mexican frontier is being sealed by the border partol and the US Army even as we speak.
Orderly, lawful immigration will continue, as will lawful commerce and tourist excursions.
But the wide open policies of the past are over, the border is being sealed tighter than a frogs back side, if one intends to cross the frontier they had better do it lawfully or they will land their felonious back side in the cooler.
Game over.
