Well lets face it, technology is making up for eroding flying skills, communications and centralised operations management make up for lack of command skills. Hence it requires less and less ability to be a professional pilot.
Airlines recognise this and hence true salaries have decreased over the past 3 decades. Sure demand will go up but so will supply. The supply will be of a generally lower quality and experience level but nonetheless adequate to fulfil the task except on relatively rare occasions.
Given the scarcity of these occasions it boils down to economic risk management. Occasionally hulls will be lost but if catered for in the planning, the risk may be acceptable.
As aircraft technologies and airports improve the remuneration for flying can only go one way.
