It's a constant theme - there's a bunch of available pilots doing other work that would consider returning given an adjustment to the salary structure.

Nursing is in a similar dilemma - except it's with instructors. To be an instructor at a university you need a PhD. Then that professor gig pays 40% below "line" nurses. Why spent the time and money to get a PhD. for a significantly lower salary? So there's a bunch of people that want to become nurses and no one to teach them. Hence, like aviation, an industry induced shortage.
