The retirement age at the inception of SS was 65. Longevity 65.
Since then with the massive amount of cash, they:
Decreased SS retirement age to 62.5.
Added spousal benefits.
Added children’s benefits.
Added disability benefits.
Added death benefits for children deceased parents.
The longevity factor has dramatically increased with out increasing retirement age.
And politicians never considered the consequences spending the surplus like a drunken sailor.
And yes, SS is a pay as you go system, the will forever cost taxpayers.
And shrug, it’s broken.
