You're REALLY using that as an argument in favor of illegal immigration? Get the fuck out of here.
No, I'm using that as yet another reason why the federal government does not want illegals to leave. I do not benefit from US Social Security, and neither do you, not yet and possibly won't in the future either. But the federal government borrows money from Social Security.
I do not, and have never favored illegal immigration. I believe it should be illegal.
