Why would someone get a fake SSN? So they can work, you mean?
So if they work using that fake SSN, and Federal/State withholding are deducted from their checks, along with Social Security and Medicare, how do these people go about getting their taxes back?
It should be of no surprise that people with fake SSN's don't file tax returns or collect Social Security when they are of age. And it's because of these contributions that are never claimed as distributed benefits that has kept things like Social Security from going under. In fact, the only reason Social Security remains afloat is because of contributions by illegals who never collect.
They are paying for some of the benefits they do receive in other areas by contributing to Federal coffers using fake SSN.
And BTW, illegal immigrants don't qualify for welfare, but even if they did, why not given they are paying in to the system just like everyone else. They rent homes and indirectly pay property taxes, they pay sales taxes when they eat and purchase, they pay gas taxes when they fill up their tank, and as stated, they pay Federal and State income taxes along with Social Security/Medicare taxes that they will never collect, so in fact they are paying more taxes than you, assuming you will collect SS when you come of age and/or have ever gotten a paid tax refund.
