Agree with most of what's already been said, but I'll throw in one more: age 67.

Great Pilot Shortage and the expected hiring boom will be mild compared to what most are expecting because, in short, the unions/workers have no power but the companies do. Companies, with the help of the gov, will pull various rabbits out of various hats (like age 67) to dampen any positive effects (for the work force) of a pilot shortage.
