I've advocated for prohibitive fines for hiring illegal aliens for decades, but such pleas have always fallen on deaf ears. Had such been enforced years ago, most of the illegals would have voluntarily gone home and tens of millions would never have come.
Of course, the demos/ACLU will sue and a TRO and probably an injunction will be issued.
The entire mess could have been avoided by simply enforcing existing laws.
Stay tuned.
