What he^said. It boils down to basic supply and demand. I reckon it's utopian for pilots to 'stick together' and take the high road on this issue. When there are 10 entry level openings for every 50 prospective candidates, you will have someone who will break ranks and grab that rare opportunity. Prisoners dilemma comes to mind.
Airlines will find ingenuous ways to extract that little bit extra from it's pilots, come to think of it, all its employees. For pilots it's P2F to bonds to self funded TR's to ramping; there are various ways to get that pound of flesh. The point of discussion is too focused on the monetary aspect of it when the opportunity cost of getting qualified and hired can and does take a heavy financial toll on newbies.
