I am really astounded at how many people on this thread don't know a damn thing about SS. You all should be embarrassed to know so little, after all to keep it safe you should have a working knowledge about how it works.
SS was designed as an insurance program. It covered the old, disabled and minor survivors. It hasn't changed much over the years.
We are now in the 75 yr of SS and they have about a 3% admin cost, which means that for every dollar it takes in .97 cents goes back to the public. Please put this into context with a private company that usually have about 15% admin costs. Most of us that collect SS are happy with the way the money is in the bank on the 3rd of the month, every month, without fail.
Yes, the government has been taking money from the trustfund. BUT it is against the law for them to just take it. They must borrow it and they put government bonds in place. These bonds pay interest and SS has been collecting that interest and putting it back into the trustfund. Those bonds are said to have the full faith and credit of the US government.
Back in 1983 they noticed that the trust fund was getting low and that the baby boomer generation was growing up so Reagan appointed a committee to come up with a solution. They raised the SS tax (FICA) and until just recently we were running a surplus. SS is NOT going broke and is NOT broken. All those cries to fix it are just people preying on your ignorance in order to get their hands on the money.
Here is the SS page on life expectancy. It is much more clear then I could make it.
