A Panel Discussion by the 1983 Greenspan Commission--"Social Security Not Primary Source Of Deficit Problems," Clip #2 [0:27]
Here's the direct link.
According to Janice Gregory, President of the National Academy of Social Insurance, "Social Security is not a major, primary source of our deficit and mandatory spending problems. It just isn't. It's nearly a flat line."
The reason that I've included this "very basic clip" is to provide readers with a knowledgeable source (Ms. Gregory) to quote, if called upon to substantiate the claim that Social Security does not contribute in a major way to the deficit.
