What other effective means do you have against a massive influx of illegals.
If it is known that large numbers of illegals are employed at some plant the logical course of action is to raid the plant, deport the illegals and arrest those who hired them.
.
I highlighted the effective action (prosecuting employers) and that can be done without a physical raid on workplaces, but Republicans refuse to seriously go after employers (because they white and rich).
Bush loved showy and expensive workplace raids but almost never prosecuted employers.
A year after Bush took office, those number dropped to below 100 and averaged around 15 findings per year and less than $100k in fines. (fixed this for contrast)
Obama switched from a focus on raids to paperwork audits of employment forms, increasing them 1600% over Bush, and increasing actual findings and fines against employers by 25,000% (you read that number correct). In fact, Clinton also went after employers, averaging 200-300 findings and millions in fines against employers each year for hiring illegals. A year after Obama took office, he had those numbers back up to over 200 findings per year, increasing 100 every year up to 600 in 2014 with $10,000-$15,000 in per year fines.
BTW, these fines are not just punishment but help to actually cover the cost of enforcement, in contrast to very expensive raids that just arrest employees and recover none of the costs.
But your right, in addition to massive fines, they should throw these employers in jail. But given the Republicans unwillingness to even fine them, they will be the first to fight such efforts.
