Flying is not for everyone. It has always been thus.
Not everyone will pass the medical.
Not everyone will pass the exams. Regardless of which system.
Not everyone has the aptitude/ coordination/ spare RAM to pick it up.
We have all seen individuals struggle - 5 or 10 or 15 attempts at an exam or flight test to qualify, then end badly shortly thereafter. Wonder why...
Fewer people now are willing, I believe, to take on a challenge where the outcome/ rewards are not certain. I think it is common across the Western World.
