I know this is a Part 121 discussion but the statement above is not completely correct. There are plenty of airmen continuing to work well past 60 (or 65 now).
Actually, you and I agree completely on the topic. There is no reason an airman's ability to work should be impeded by the regulation. This is what I said, and yes, it's completely correct. Therefore, I'll say it again: Age 65 is wrong too, in that it also prescribes an artificial restriction on an airman's ability to work, which is unwarranted.
Yes, I got that part about both being wrong but that is where the similarities end.
Even Christ's analogies were far from perfect, and weren't intended to be universal Let's keep it in context. UndauntedFlyer made no statement regarding comparing age 60 to slavery. He said that slavery is wrong, and that the age 60 restriction was wrong. Both have been done away. Any effort on your part to carry it beyond that is reading into his statement what's not there, and putting words in his mouth.
However...
You asked a question which should be addressed...
If you didn't like Age 60 then you could get a job somewhere else.
All good and well unless you're 60 and put on the street...where nobody will hire you. Even though you may have another fifteen years or more of good work left in you. Age 60 limits took away a man's ability to keep working in a job and field where his longevity and skill made him a valuable asset. Age 65 does the same thing, just five years later.
If a man is restricted by high blood pressure or bad eyesight, that's one thing. But his age? Utter nonsense.
Your comparison between age 60 and slavery, likewise, is beyond the mark and also nonsense. It's out of context and inappropriate. It's a comparison that only you have made. Accordingly, you're arguing with yourself. Hardly a productive endeavor.
