Awaiting the heat........
No heat from me or many here - I agree with you. - it's training, training, training, all the way down and robust check rides that go back to high standards and being brought along by instructors who know the airplane inside and out.
When introduced, the 320 then 330/340 series required a new understanding of how flight controls and automation worked - the airplane is obscure and confusing only if a student was offered barebones groundschool and eight simulator sessions before flying the airplane under supervision.
For the vast majority of new candidates being hired, there is nothing "wrong" with today's young pilots that an appropriate level of training and experience gained under supervision can't address. "Success" has perhaps curiously been flight safety's biggest enemy, the temptation being to "fine-tune" expensive programs and standards on the back of a superb historical record, (forgetting how that record was achieved).
