It’s technically not a ponzi, it’s just a standard pay-as-you-go system which requires some sort of growth in revenues (such as population growth or changes in taxation) to be sustainable.
A ponzi scheme is fraud that can never pay out what it promised.
It can also be sustainable if the surplus during population growth are invested and not spent.
Somehow with these systems governments are very silent when they can skim off the top because more people are paying in and they can use that money to patch other holes in the budget, but they somehow become very critical of the system once that money would need to be paid back from the budget.
