I'm sure that by 1974, Ayn Rand was at least 65 years old, and so that was social security retirement, to which she had contributed.
It surprises me, the amount, though--$11,000 in a little over seven years?
Maybe we should scale the retarded cross-eyed Iowa primitive's, and the subway cat's, and the worthless freeloading bum the wily primitive's payments back to something like that, so as to save the disability money for those who honestly need it.
