One of my mothers friends, who is now in her 80's, has been retired on a pension for over 40 years. She started working for her municipality right out of high school at 18, and worked 25 years as a clerk to get a full pension. Retired at 43(!) with 75% final pay (annually adjusted) and lifelong medical benefits.
Its totally insane and completely unsustainable. Back in the day people usually keeled over at 65 and the US was viewed as having achieved infinite growth forever, so perhaps back then it was a reasonable but generous offer. Today however it's just straight up corruption and waste to offer benefits like that.
I don’t think that retired fire chief’s (or school teachers') retirement is what’s wrong: what’s wrong is that most of us will not have a retirement that good. Why is that? It is possible to answer that question without tearing down someone else’s situation.
Everyone who gives a company years of their life should be able to comfortably retire after decades of service, but companies have managed to convince workers that most of them should work until the day they die and only a small precious few deserve to retire and finally be allowed to spend time with their loved ones.
