The other problem is of course is that there are many student pilots who aren't really suited to professional flying who are however "suitably qualified".
People get so far down the line with so much money invested and time and "dreams" that they carry on into professional training.
They struggle through their CPL and IR training the schools keep flying them, although the school knows that they probably wouldn't recommend them for job if push comes to shove other than providing the mandatory airside pass reference.
Although there are many applicants for such jobs, the vast majority are qualified licence wise but are horribly under skilled. The problem is - they refuse to accept this themselves - and these "pilots" accept whatever flying job they can get and accept any related conditions.
