I would suggest that you read the report on the over-run of Bangkok by a Qantas B747-400 to see that it is not only F/E's who screw up.
You are mixing apples and oranges, Old Fella.
Qantas has very experienced and well trained
crew, not just Captains.
However, some airlines are not so fortunate, and have rather junior folks assigned, and therefore rely on their very experienced expat Captains to handle adverse situations.
As one fleet manager told me, personally...'we
know the limitations of our more junior guys, that's why you're here, and likely will remain, so long as you so choose.'
