Social Security turning 80: How much time is left?

Social Security turns 80 on Friday, and the massive retirement and disability program is showing its age.

Social Security’s disability fund is projected to run dry next year. The retirement fund has enough money to pay full benefits until 2035. But once the fund is depleted, the shortfalls are enormous.

The stakes are huge: Nearly 60 million retirees, disabled workers, spouses and children get monthly Social Security payments, a number that is projected to grow to 90 million over the next two decades.

And the timing is bad: Social Security faces these problems as fewer employers are offering traditional pensions, forcing older workers to think hard about how they will afford retirement.
