If you take the emotion out of blindly hating management, this is correct. Many of these people have generic transferrable skills (eg "Change Management", "Wellbeing Advisor" "Transformational Lead") and no often no real passion for aviation. I'm sure many were happy to take a lower salary packet in exchange for that higher onload category. Not so helpful in the current times..
Well those people can go and leave and I am sure they can recruit many suitable candidates. I find it amusing that the narrative is that there is a oversupply of highly specialised highly trained pilots ( whose qualifications in the current market would cost you $120K+ to actually get then 5 years experience at least) but always an undersupply of people where all you need is a business related degree and some relevant experience and you're qualified to apply. Then if they run out of local candidates you then have the entire planet to recruit from.
I'm sorry but you are not "special" just because you work in management. Generally most people can easily be replaced there are actually very few positions where this is not the case and most of those are usually highly specialised, highly skilled/qualified. And no pilots do not fall into that category.
