I don't people fully realize just how horrific and traumatic a mass deportation would be. You'd have families getting dragged out onto streets of American cities and towns, you'd have workplaces raided and emptied, you'd see holding pens full of men, women, and children. The economy would collapse. Legal immigrants, legal asylum seekers, even American citizens would be caught up in the mayhem. It would absolutely chill America and destroy our reputation globally. Highly trained immigrants with advanced degrees would no longer come to the US to live and work. There would be an exodus of Americans who don't want to live under such terrifying conditions.
