All the drives towards even more automation, checklists, and safeguards would be understandable if we were picking Joe Public up off the street and putting him into an ariline cockpit, but we're not. In almost all countries, the ATPL requirements require (quite rightly) some of the most demanding criteria for training and subsequent employment there are. The medical and requalification standards ensure that the high level of professionalism attained are adhered to. That always seems to be overlooked following an accident or incident, the fact that in general, these are well above average individuals who are trained to a very high level.
As jondc9 suggests, instead of making everything so Micky Mouse that this degree of training is not required, why not instead leverage that above average ability to better understand the failures attributable to the human condition, and recognize risk scenario's before all the unrelated events align and cause an accident. CRM was widely scorned when it was first introduced, with a lot of unprofessional attitudes towards joint problem solving and work share in the cockpit, but eventually it was recognized as a valuable tool for flight safety. Is it not now time to apply the same initiatives towards risk management and accident avoidance training?
