LOL!! Yeah, they'd simply leave all the fertile land in America, and all the infrastructure here to go to 3rd world dumps so they could hire 3rd worlders. LMAO!!
What would happen "if my scenario played out" would be precisely what happened before when things were as I suggest. Prior to the immigration reform acts, and back when border security was reasonably enforced our conditions were much better, relative to technology.
We've had deportations before because of economic problems and job shortages, and it worked great. Oh, and all the companies didn't leave the nation. LOL!!
Operation Wetback was a 1954 operation by the United States Immigration and Naturalization Service (INS) to remove illegal persons from the southwestern United States, focusing on Mexican nationals.
Burgeoning numbers of illegal alien Mexicans prompted President Dwight D. Eisenhower to appoint longtime friends John Cox and General Joseph Swing as INS Commissioner. According to Attorney General Herbert Brownell, Jr., Eisenhower had a sense of urgency about illegal immigration upon taking office. In a letter to Sen. J. William Fulbright, received at his Villa Portofino office, Eisenhower quoted a report in The New York Times that said, "The rise in illegal border-crossing by Mexican "wetbacks" (rooted from the watery route taken by the Mexican nationals across the Rio Grande) to a current rate of more than 1,000,000 cases a year has been accompanied by a curious relaxation in ethical standards extending all the way from the farmer-exploiters of this contraband labor to the highest levels of the Federal Government."[2]
The operation was modeled after a program that came to be termed the Mexican Repatriation, which put pressure on citizens of Mexico to return home during the Great Depression, due to the economic crisis in the United States.
The effort began in California and Arizona, and coordinated 1075 Border Patrol agents, along with state and local police agencies, to mount an aggressive crackdown. Tactics employed included going as far as systematic police sweeps of Mexican-American neighborhoods, and using racial profiling on random stops and ID checks of "Mexican-looking" people in a region with many Native Americans and native Hispanics. In some cases, illegal aliens were deported along with their American-born children.
Some 750 agents targeted agricultural areas with a goal of 1,000 apprehensions per day. By the end of July, over 50,000 illegal aliens were caught in the two states. An estimated 488,000 illegal aliens are believed to have left voluntarily, for fear of being apprehended. By September, 80,000 had been taken into custody in Texas, and the INS estimated that 500,000 to 700,000 had left Texas of their own accord. To discourage illicit re-entry, buses and trains took many deportees deep within Mexican territory before releasing them.
Tens of thousands more were deported by two chartered ships: the Emancipation and the Mercurio. The ships ferried them from Port Isabel, Texas, to Veracruz, Mexico, more than 500 mi (800 km) to the south. Some were taken as far as 1000 mi (1600 km). Deportation by sea was ended after seven deportees jumped overboard from the Mercurio and drowned, provoking a mutiny that led to a public outcry in Mexico.

As you can see, once we start shipping them out, most will leave voluntarily.
Quote from denner:
You are the leftist and don't even know it. I'll tell you exactly what would happen if your scenario played out. More companies would simply leave the country. What you are advocating is basically the same thing that the unions have tried to put in place for decades. Every state with strong unions and the bought and paid for Democratic party is millions in debt with catastrophically underfunded pension plans.
Again, I ask you how does our country compete in a global stage when so many others have workers literally working for peanuts?
