I agree with lazs......make a mandatory waiting period, punish employers who violate hiring laws.....dunno if jail time would suffice though.
Confiscating any and all business related equipment would put a dent in their ability to get anything done at all. Take their work trucks, their tractors, plows, spraying equipment, etc.....anything that has to do with their job, gets confiscated and held until they show evidence of 100% compliance with employment laws.
I'm all for any measures that stem the flow of or eliminate the flow of illegal immigrants.
I've worked enough places to know that many, not all, of them know more about the loopholes than we do, and work them to the max.
Case in point:
Worked in a plant that made hams and bacon and other pork related products about 10 years ago.
Talked to the HR people and they told me that nearly 75% of the workers we had did NOT speak English, were not "legal" when they were hired, but they had a kid here in the US and being the parents of an American citizen, well.......all kinds of neat stuff opened up for them.
The system, as it is now, has no teeth, offers no real incentives to become legal or an American citizen, and favors the illegals. Have a couple kids here and the system absorbs them and practically subsidizes their being here.
The ones I managed to get to talk with actually laughed at me, as they were sending a lot of their paychecks each week back to Mexico to their extended families, all the while drawing Welfare or other government checks, and living better than most of the natural born citizens working there.
I mean, one actually told me, almost verbatim, that it paid him to have more kids, cause the government checks just got larger with every child, and that made him able to send more back to Mexico. We were working 80-100 hours a week, working 7 days a week, and he said he could pay all his bills with what he made on about 30 of those hours. The rest went back to Mexico, where the exchange rate allowed his relatives to live pretty well.
Mexico has the natural resources to make their economy attractive enough to keep workers from doing anything and everything to get into this country....the government is just too lazy and corrupt to do it. Far easier to just leave things as they are and be a sponge on their northern neighbor.
Just my thoughts, nothing more..........
