What if all the immigrants leave America

Let's say for some reason Trump gets his wish all the undocumented immigrants leave and hell basically any group he doesn't like (documented or undocumented any group/race/background) just goes somewhere else.

How does America fair? I'm thinking not well considering most people won't wanna do the jobs left open at the same rate or at all.

Food takes a nosedive. Culture etc.

Edit: I forgot bout wages, I assume they'll eventually go up at least if hope so, but idk wages have yet to reflect the cost of living.
