Well here in the UK the state pension age has risen to between 67 - 69 depending on your date of birth, few if any pilots jobs now come with final salary pensions, many pilots have had more than a handful of jobs so have little pensions with different providers and the state pension is now flat more or less anyway, so despite pouring huge amounts into HRC through our taxes you’ll get the same money as the lay about down the road.
Personally I have no great wish to go on and on, but I feel that so long as you pass your medical and 6 monthly sim check why make it mandatory?
The taking jobs off the young is a red herring, at worst it might delay but once you catch up with the retirement cycle it makes no odds, airline growth or lack of is a bigger threat to the young ones and many 19 year old pilots would benefit from having done something else, they would certainly moan less if they had worked in the real world.
