Actually it is. Pyramid schemes ALWAYS end up collapsing, and this one will too. Interestingly, the defense of the left and the SS Administration in defending the pyramid scheme of the Social Security system is that it is not a "Ponzie" scheme, because in a fraudulent pyramid scheme the participants are not aware that it's a pyramid scheme, and think they are actually getting real returns as if it were a pension or an actual investment plan. They say it is perfectly legal because everyone knows it's a pyramid scheme that is fundamentally unsustainable.
It has been thus so that the government can raid all the payments and spend them on whatever it wanted, just like the criminals running a Ponzie scheme spend all the funds on mink coats, mansions, and cars. Unfortunately for us it will not end till it collapses, because the criminals are in charge and everyone wunts muh SS dat I pade into. Fucking ridiculous!
