In a market these days were there is a far larger demand than 'back then' there is no NEED to pay for a rating or training etc..
I do NOT agree that these retirees are by any means to blame for the lower salaries or payin4trainin'. You said it yourself, they work at FH (as skippers, not having paid a penny to MOL) or you'll find in JAL/ANA/SQ/KAL contracts maybe which are wayyyyyyyy off for the wannabee and not that badly paid if I may say so.
Just my point of view.
