About 2 days after the first employers started getting charged for the crimes they're committing, every other employer would go bug-eyed and tell their illegal labor "sorry, you don't work here any more" ...
It would be disruptive and tumultuous. A whole lot of tomatoes would go unpicked and would rot in the field, this year. You'd have to mow your own stupid lawn.
AND THEN when it became clear there was no legal labor pool to do these jobs - whether important agriculture & construction, trivial tasks like daily towel exchanges at the Motel 6, or unimportant landscaping for people like you - a real, comprehensive, guest worker program could kick off and allow these illegal undocumented immigrants to register. They could move out of the dangerous shadows, pay taxes, enjoy workplace protections that legal workers enjoy and all workers deserve, not be vulnerable to slum lords who maintain substandard housing for poor immigrants because they have no recourse, quit looking over their shoulder for ICE.
I'm not saying people wouldn't **** themselves for the first weeks/months. I'm saying this is a solution.
You're right - they ARE overwhelmingly good people, hardworking people. They are contributing to the economy. We should be glad people are coming here to realize the American Dream, to work hard, to build better lives for themselves and the rest of us.
Consider the possibility that you're exploiting vulnerable people who are working for you, without benefits, without safety oversight or options for whistleblowing. All to save a few bucks getting your grass cut. Don't pretend you're taking the high road here, by demanding that the cost of the healthcare they might need if they get hurt working for you be distributed to the public.
Edit - I need to chill out a little bit.
