I'll tell you where the system is also wrong.
Apart from the military or cadet ships, unless you are from a relatively well off family, you wont get a look in for an EASA licence, simple. So we've "weeded out" probably a lot of very suitable people right there. In my day the pick of the bunch were the "hard sloggers", with the drive and determination to press on in the event of failure for e.g., Who went the extra mile to pass the examinations etc. Who were given a crack at getting into the "big time" via the self improver route or a 150 hour approved course CPL, in some countries. This would allow them to get useful aviation related employment allowing them to upgrade themselves. This now seems to be out the window. What percentage of wannabes can afford an upfront fee of at least £60K for an EASA licence?? This is where the system has gone wrong. This is the reason, a lot of the wrong people are getting in, albeit some areas are worse than others.
At the beginning of the JAA the Germans wanted anyone eligible for a JAA licence to have an appropriate degree at university. What utter tosh! Fortunately the dear old UKCAA put their foot down and said as much.
Test flying of course is another completely different story.
