In this day and age supply and demand is a one way street. Anytime there is a surplus of skilled labor, wages are pushed down. However, any shortages are usually remedied by either decreasing the entry requirements or increasing the availablity of visas for foreign workers. Either way wages are held down.
If airlines cannot attracted qualified applicants for crap wages the last thing they will do is offer to increase pay in any meaningfull way. My guess is that they will start ab-initio training programs which will require some sort of long term contract.
