Facts about Social Security Finances
Let me clear something up since some are saying social security is not adding to the deficit.
Social security was running a surplus unitl 2010. The excess money was put into trust funds. Now that social security is no longer running a surplus it has to take money from the trust funds to help pay social security recipients. Congress was also borrowing money from the trust funds to help decrease, or in reality, hide the debt. Of course you can't borrow money to decrease your overall debt. Our overall budget deficit always was the budget deficit minus the the social security trust funds surplus being borrowed.
Now that the social security program has to take from it's savings(trust funds) congress will not be able to borrow from it as much, thus increasing the deficit. So technically speaking, the social security program added to the deficit even when it was running less of a surplus because if it ran more of a surplus we could borrow more, essentially from ourselves, to pay down our debt.
