It's time to put an end to this crap. Turning a blind eye does not make it right!
I am not saying turn a blind eye. I am just saying that coming down hard on small businesses that use illegals is going to put a lot of them out of business long before the illegal problem is solved.
Some business people will comply and lose out in the ultra competetive marketplace, other businesses will flaunt the law just like they do now.
If we want to end the use of illegals in the home trades, then fine any property owner who allows illegals to work on their property. The onus will be on the customer, most of whom will make darned sure they don't hire companies that use illegals. The marketplace will weed out illegals and the companies that use them in a very short time. Of course I don't think that idea would fly and it probably isn't lawful anyway but I think it would solve the problem.
Illegal aliens should either voluntarily return to their home country or be deported.
