Trafalgar, why don’t you actually ask, (not preach to) the newbie SO’s or DE FOs, you meet, and see if they are enjoying their time in CX ? Ask them if they want to return to their previous careers consigned to regional TP flying , for a pittance. You will find the answer unanimously is that the newbies are here for their careers . And wether you like it or not , the newbies are the future, not you mate. Move on and for better or worse, let the next gen have their experience. Retire. Take your millions.
FYI, least we've all forgotten Career : an occupation undertaken for a significant period of a person's life and with opportunities for progress.
Long haul , career airline. Not many left you can just walk into . Unless you know better?
