This actually seems like a bit of satire, to be honest.

Hiring illegals is, actually, a win-win for corporations. That is why they do it. Which is also why you have to stop them from doing it.

• Since you're paying them, illegally, under the table, you aren't going to pay tax.
• Since they don't speak English, and are foreign, they can't use the legal system against you for exploiting them.
• Since they are now utterly dependent on you for any financial security, they are going to work hard to make sure they can't lose that job

The win for the illegal is that he gets money to send back remittances.

Hence, it's a win-win.

You should stop illegal immigration because of literally all those reasons. The better solution is to bring up criminal charges against the employer (which almost never happens), and to loosen regulations against domestic labor, including cutting payroll tax.
