SS brings in more money than it pays out. The only problem is that they raid the SS funds to pay for other things not related to Social Security. These people are thieves.
Apparently, SS brings in about $50 billion per month, and has obligations for about $29 billion per month. Thus, the obligations can indeed be paid, leaving $21 billion for zer0's favorite planned parenthood abortions, PBS, ACORN or the like. Furthermore, SS merely sends the tapes with the check info to the Treasury dept (aka, Geitner/zer0). No question on whose doorstep any non-payment of SS resides.
