We have to get control of our borders. You can only do that if you make companies obey the law and not hire undocumented or illegals. They can only do that is if they have a Social Security Card that has biometrics so they know whether the person is legal or not.
Most illegals are without health insurance and when these workers need emergency healthcare the American taxpayer gets stuck with the bill.
We try we fail we posture we aspire we pontificate - and then we age shrink die and vanish.
