Want more pilots? Do whatever it takes to get 90% of students to PTS-level in a single season. The student drop out rate is abysmal. Everyone's entire investment goes down the toilet when that happens and it is disheartening to everyone who carries on.

I'm pretty sure that this is possible and that there are people who know how to do it. It would mean making some changes to how things are done.

(Not to take anything away from the other good ideas mentioned in this thread.)
