They actually didn't intend to; it was supposed to have around a decade of money paid in before any started going out. Also, though, remember that it didn't cover the same people it covers now.
Can we go back to a scheme where we have a decade of money paid in? I'd happily pay a little more if it helps end the endless name calling and what not.
I found it interesting that the system looks to be in far better shape today than it has been for many decades. In the early ears, assets outweighed expenditures by a huge amount, sometimes by more than a factor of 10. As you move down the table, this stops, and in the 1970s it hits a 1:1 ratio of yearly expenditures to assets, then shoots way past. In 1983, the trust fund had under $20 billion in assets but the program spent $153 billion! That's clearly a program where current taxpayers are paying for current retirees, rather than the savings program it's painted as.
By the late 80s, things start looking much better, as income substantially outweighs expenditures. In 2001, the trust fund exceeded $1 trillion while expenditures were at a considerably more modest $378 billion. The 2013 figure has about $2.7 trillion in the trust fund, with expenditures of about $679 billion. Not a factor of 10, but certainly far better than the 60s, 70s, or 80s.
I knew that SS was in better shape than many people say, but I had no idea that it used to be so much worse. The picture painted by the naysayers is one of a long slide towards disaster, whereas it looks like the program is currently doing great. Future demographic shifts will certainly hurt a lot, but compared to the years when the trust fund was essentially nonexistent there's almost nothing to worry about.
I didn't know this was the case. Why would they start paying out as soon as they started collecting? It makes no sense to me.
