As a female pilot from a low socioeconomic background who has been involved in aviation since I was a teen, I have seldom experienced any issues. Work hard, respect your peers, don't take yourself too seriously and remember, LADIES and gentlemen are involved in this amazing industry and on PPRUNE - just poking fun at your opening post
As for a cadet programs, I really don't think it will happen. As many here have mentioned, go your own way and you will find a path. Good luck!
