Unfortunately, what Cato says is very worrying (1). Primarily, they highlight court cases in which Social Security is pulled away from people, and reaffirmed by SCOTUS. This is the troubling quote:
The Court’s decision was not surprising. In an earlier case, Helvering v. Davis (1937), the Court had ruled that Social Security was not a contributory insurance program, saying, “The proceeds of both the employee and employer taxes are to be paid into the Treasury like any other internal revenue generally, and are not earmarked in any way.”
We would likely have a national riot if Social Security was just yanked at once. But if my own life is any guess, the age to qualify for "benefits" keeps going higher and higher. It's theft by attrition, and backed as not theft by courts.
I do not agree with CATO's eventual policy of "privatization" at all. The other choice, which was not posited, was to earmark the funds, keep them segregated from the general fund. Then do the right thing and set Social Security as a guarantee at the same age for everyone. And, remove that cap.
