SSI is on a path to disasater. Unfortunately, anyone who suggests any real change to the program is demagogued to political death.
When the program was started, the earliest benefit age was one year older than the avg lifespan. There were well over 10 people paying in for each beneficiary. Seems like it is something like 6:1 now and according to our population trends is headed toward 3:1.
Simply said: it is unsustainable.
Sidenote: If SSI is not only legal but a "right"... then why is Bernie Maddoff in jail? It operates on exactly the same concept as a Ponzi Scheme.
