Spare me!! How about the TRUTH? Law-breaking, ILLEGAL alien is about as truthful as it gets! It matters not if they are "necessary" or "essential" workers. They are welcome to come and do those jobs "American's won't do" AFTER applying for a green-card, being granted permission to be here and obeying our laws!!
It isn't about scaring anyone. It's about telling the truth...and the turth is those who come here without permission are ILLEGAL aliens.
They are necessary if this guy needs someone to wait on his table or pick lettuce. If they get uppity and threaten his job, though, well that would be just unacceptable.
