A little known fact is that a lot of illegal immigrants that work in this country do indeed contribute to social security. Many of them will pay 50-100 bucks and get a fake SS card and ID from a forger upon arriving here and with that they will begin work somewhere. Once hired with the fake documents, many of them will fill out a W2 just like a legal employee does and when they get paid, money is withheld from their checks just like the money that is withheld from everybody else's check that works as an employee somewhere. However, in their case, since their identity is forged, they NEVER CLAIM THAT MONEY BACK, which, given their small incomes for the most part, they would, at least in part and if they were citizens, be able to do. So, what ends up happening is that the IRS usually ends a fiscal year with a huge stash of "uncollected" money that sits there and then is put to other government uses (some say that uncollected taxes by these workers pile up to the tune of 7 billion dollars in the IRS coffers, some say way more than that).

A lot of people are under the impression that ALL illegals work under the table. That is absolutely not the case. Many do, it's true. But just as many work with fake documents, a situation which is not usually brought to light...

I obviously don't condone illegal immigration to this country or the forgery of documents and other ways of breaking American law. My point is to simply say that many of these people do contirbute to the American system via their taxed income.
