Everyone wants employers of illegals shut down, except the ones in their town.
Companies pay the bulk of local ad valorum taxes, not working stiffs. Many of the employers of illegals also employ citizens, often times in good paying white collar positions.
But there is a lot of stress involved in hiring illegals. Not just the civil and criminal liability, but problems with bonding and insurance. Illegals usually don't drive and thus may have trouble getting to job sites.
They can't get licenses required to do basic mechanical work such as handling refrigerants or chemicals. They may get busted by ICE or mugged for the cash they have to carry.
If legal employees were available, I don't think anyone would to go through the stress of hiring illegals.
I would find this more believe-able if there was not so much evidence that wages are falling in job categories that used to put American citizens in the bottom end of the middle class. But wages for things like framing, dry wall hanging, roofing etc have seen 25% to 50% reductions in areas where illegals are colonizing these job categories.
If there was a labor shortage wouldn't common sense and the laws of supply and demand suggest that wages would be going up?
