Thing is some people (or their parents) make that investment without doing the research into what sort of return they will get on that investment in the early stages and then whinge about it.
Some people get offered a starter job for below award wages, agree to it,
shake hands on it...and then whinge about it.
I suppose these whingers fell for the scam that if they learn to fly at school "x" they are guaranteed a job with Qantas as soon as they get their licence as "there is a worldwide shortage of pilots" blah blah blah
Some people have the sense and self esteem to walk away from a potentially exploitative situation like that without taking that job, get on with their careers and recognise the importance of keeping ears open, mouth shut and networking.
