I'm very liberal, but I don't see this as
screwing the retirees. I think they got a better than they should have deal. The unions over-reached and they got rates of return that were unsustainable. We haven't even talked about the gaming of the system that happens (punching up salary for the last year, so their retirement benefit goes up).
The police chief in a town near mine retired on something like $300-400K and it was discovered that he had taken a job at another city, several hundred miles away.
There is so much corruption and abuse of the municipal retirement plans that I think a reboot is in order.
