The idiot politicians pay government “workers” more and give them big benefit packages to “earn” their votes. It works. Unfortunately, they are using OPM (other peoples’ money) to do this. Just look at the competence of the average government “worker”. I laugh at the criminals.
Defined Benefit Plans, especially those in the public sector, are built on quicksand. The actuaries never could keep up with the promises politicians made to union bosses in exchange for votes.
It’s a house of cards.
