The viability of the Social Security system must be protected for those who need it. The system was intended to help the elderly poor and the disabled. Not all of our elderly are poor. A voluntary system should be instituted allowing those who can afford to do so, to return their Social Security payments.
I, like millions of other Americans paid into the system, and shouldn't be denied the money I put into it. (Not to mention the fact that children who lost parents deserve money too.)
