The large population of illegal immigrants in the United States has greatly contributed to the Social Security fund. The Chief Actuary of the Social Security Administration estimated that by 2007, the Social Security trust fund had received a net benefit of somewhere between $120 billion and $240 billion from illegal immigrants in the US. The Social Security crisis we face now would be far worse if not for the contribution made by illegal immigrants. Ironically though, it is the people that benefit most from and receive social security that want to force illegal immigrants out of the country.
The recent decline in illegal immigration due to tighter restrictions and hostile attitudes ultimately means that the contributions to Social Security from illegal immigrants will decrease as well.
