Pretty much any time in human history where someone has tried to displace that many people, they’ve either failed or it turned into an ethnic cleansing.

Let’s say you suddenly got yanked from your home and sent to live in the land of your ancestors (where you don’t have a home or any friends). Would you survive?

If yes, ask yourself again, but now you’re broke and have a medical condition and you require medication to survive. How about now?

These people getting deported don’t have 2nd homes they can return to, and they can’t just put one on a credit card.

Don’t like homelessness? Mass deportation creates homelessness crises.
