Until this year, Social Security took in more money than it paid out.
From the sources I posted here it started some running deficits in early 2009 when unemployment skyrocketed, then December-January this year FICA tax got cut and it went in deep red.
I was posting that FICA was the stupidist tax to cut, esp if you can only cut one tax. Yet Dems stick to their talking points about it paying for itself.
