The roots of the public pension mess are easy to understand: The money set aside wasn't enough to cover promised retirement benefits.
Compounding matters was a failure to adjust the equation before a math problem morphed into a fiscal monster.
Social Security could find itself in the same predicament unless policymakers apply the lessons from the pension crisis.
If they act responsibly, which means acting quickly, they can ensure the solvency of Social Security for decades to come by making relatively minor adjustments to revenue, benefits, eligibility or, perhaps, all three.
A week ago, the Obama administration issued an annual financial report on Social Security, forecasting that the retirement trust fund will be exhausted in 2033, three years sooner than was projected a year ago.
The report cited two primary factors: Taxable earnings dropped 1.6 percent because of the weak economy, and recipients were granted a 3.6 percent cost-of-living increase.
Even so, Social Security collected $69 billion more in revenue and interest last year than it paid out in benefits. And, as Commissioner Michael Astrue pointed out, Social Security could continue to pay about 75 percent of benefits due after 2033 even if no adjustments are made.
"That's not acceptable, but it's still a fact that there will still be substantial assets there," he said.
This is an election year, so chances are Congress and the presidential candidates will squabble over which party will throw seniors to the wolves rather than addressing the projected shortfall. But the sooner they address Social Security, the easier it will be to set it on a healthy financial course.
It's been 29 years since the last significant change. At that time, Congress raised payroll taxes and gradually increased the age for eligibility to prepare for the baby boom generation's retirement.
