You would think so but the IRS doesn't care. As long as the money keeps rolling in they turn a blind eye to the duplicates and never notify ICE. They also provide "Taxpayer ID Numbers" for people who don't/can't supply a valid Social Security number. They are useful for filing tax forms and opening bank accounts. Why any legal citizen would need one is open to debate, but there you have it; the IRS is complicit with the illegal immigrant in providing semi legal documentation.

What we will have to start doing is fingerprinting EVERYONE for EVERY JOB, so that employers are sure who they are hiring. It would be expensive for the employer, but maybe the government could chip in to defray the cost. Then, if a person turns out to be an illegal, the authorities could be notified and the illegal exported. Also, by checking the fingerprints in the criminal databases, criminals could be identified and their sorry rear-ends could be put in prison. Does this make too much sense to be supported by our government??
