No!
We’re not legalizing them for a thousand bucks.
They’re costing us far more than that each year they are here.
Send them home.
Allow them to work here seasonally with the farmers.
Families stay home in Mexico.
The point is they are illegal. There is no amount of money that makes them law-abiding, now that they've shown their colors - that of willingness to violate the law. What's next... can criminals pay various amounts to wipe out misdemeanors and felonies? How much for robbery? rape? murder?
They need to get the heck back. They can wait to be deported (and registered illegal to never return). Or, do so on their own. The latter has the advantage of them being free to get in line legally from their home country - since there is no record of them being here.
