You don't understand how SS works. It is a pay as you go system. Any "surplus" in terms of revenue versus payments is used for other purposes and an IOU placed in the SSTF, which is part of the national debt and considered "intragovernmental holdings." Starting in FY 2008, the "surplus" starts declining and in 2017 we will be paying out more than is coming in. We will have to borrow real money to redeem the phony non-market T-bills in the SSTF.
The costs of illegals are being borne by the hospitals, educational system, penal system, and social welfare system. The cheap, exploited labor serves to depress wages at the lower end of the economic scale for American citizens. Over the past six years, the median household income has declined
The median household income in 1950 was $3,800/year.
That translates to $33,166 in 2004, a touch more in 2006.
A Philco television set cost $199, or roughly 5% of a year's income. I can get a 32" digital TV today for $299, or less than 1% of those $33,166.
With the possible exception of housing (and th average size of the homes in tyhe US has increased since the 1950's), our wages buy much more today than they did then.
As far as understanding how SS works, I quoted government sources.
Then again, if you're a high school dropout in this economy, competition from illegal aliens is the least of your problems.
