Are the days of the "Two Wing Master Race" coming to an end?
Heck no! Perhaps its just that less of them are staying on to 'climb the greasy pole' very far. Pilots have skills that carry over directly into the civvy world, with reasonable pay, if you can be arsed to get the license. Navigating/WSOing doesn't really carry over
directly but, of course, plenty of Navs/WSOs (and Pilots, but to a lesser degree?)) do other stuff in civvy street. I think Navs/WSOs are aware that they would have to do something
really special to earn that sort of money in civvy street, so they fall over eachother to 'climb the greasy pole' and hence the predominance of them showing up in elevated positions ...... IMHO.
