Hmm.. the Captain who obviously knew what he was doing, ignored his junior flight deck member who was aware of the situation.
The "kid with 200hrs" would have saved 152 lives, but the Captain ended them.
That may be the case however it is likely only an extremely small part of the story. There is absolutely no doubt that experience improves safety. Not just in aviation but almost every endeavour. To suggest otherwise is complete foolishness.
