The problem is that not enough people do walk away from the industry. They spend a long time trying to win their dream flying job, after a couple years the decide they really don't like it but done know anything else, stick it out for a few mote years, really start to dislike all the bad stuff that they overLooked for years, decide that it's all too hard to do anything else so they stay in and see out their careers all bitter and angry....and probably divorced.
There are plenty of really good careers out there that pay better and offer better lifestyle options. The advent of low cost airlines means pilots, engineers, ground crew, cabin crew, company managers and aircraft all have to work harder for a bit less. That's the way it is.
I just wish that more of the private school princesses and burned out divorced complainers would just quit and do something else instead of spending decades crying and sooking about circumstances that they themselves created though lack of positive action When they had the chance. I feel no sympathy for them and lord knows there are lots of them!
