The cost of living adjustment for Social Security recipients next year is one of the lowest since 1975. But that hardly matters to critics -- who worry the giant entitlement won't pay off for many of us.

Tad Dehaven at the Cato Institute says there's no way Social Security survives without massive changes.

"Because of our changing demographics you won't have enough workers to pay all of the benefits. Yes, something will need to be done about that."

Dehaven is not optimistic.

"Younger and younger generations going forward are basically getting a bum deal. They're paying lots of taxes for benefits to go to retirees and it's only gonna get worse."

But Dean Baker at the more liberal Center for Economic and Policy Research says Congress won't let Social Security crash.

"Congress people have to go back and get re-elected so, the idea we're gonna hit the wall and there'll be nothing there -- that doesn't make any sense."

Baker says we faced a Social Security crisis in 1983 with a republican President and democratic Congress and they were able to work out a deal.
