If you will permit me to coment from an alternative perspective, the people who appear to have failed are the Irish Aviation Authorities.
They have pandered to Ryanair from day one and despite the totally bleeding obvious staring them in the face, they fail to act in any way.
Other national authorities (the UK CAA et al'), who are strong enough to face up to the likes of MOL but can do little about it outwith the UK, the Irish CAA prefer to behave like ostriches, or even worse, (yellow is the term some may choose to use).
Meanwhile, Ryanair will never be short of pilots or cabin crew because those who want get on know they can get paid a reasonable salary for working hard and in return they get a stepping stone for better things.
Remarkably, that's not too different from the majority of other airlines in the same, or other sectors.
