Remember the Hyundai raid in Georgia, back in September? Caused all kinds of problems for them when their efforts ended up jeopardizing the operations of the factory.

But that wouldn't happen. Follow me here:

step 1 - pass the law against hiring undocumented workers. Fine is $10K per worker. (Arbitrary...make it more, if you like.)
step 2 - give companies time to get their ducks in a row, e.g. sign-up with e-Verify (my company used that)
step 3 - any raid will almost certainly not find anyone because companies aren't going to want to pay the stiff fines

If they are relying on undocumented labor, then there's a problem. Either labor getting documents, or the desire to exploit the labor.

If MAGA isn't happy with that, then they're hypocrites. I know some on the far-left won't like it, but the "let everyone in" wing of the party is pretty small. The right should be thrilled. If they aren't, then they don't really want the problem fixed (which is what I suspect because of things like the Hyundai factory you mentioned, and the "pausing" of raids).

Then you can get political and call them out to their MAGA-ite supporters, and maybe take over enough of government to get actual reforms (like affordable worker visas that don't have a path to citizenship, DREAMERs, etc.). Again, the right should like the no-path-to-citizenship bit...I'm trying to be reasonable and compromise.
