They tried that over here with Brexit. Those darned immigrants stealing our jobs (while also just living off benefits, of course). EU citizens were like, screw this. They left, suddenly farmers were faced with their produce rotting in the fields, because guess what? The Brits don't actually want to do those jobs.

So what do you think happened next? They had to allow special visas to lure immigrants back in.

Meanwhile, the gammons were still raging that immigrants lower wages because they'll work for less pay than UK citizens.
