OK, I am going to be flamed for this but I have to ask it here and not while being an SLF between flights.
While I have every respect for the captain's authority and the fact that he signed for the aircraft let along that an avoidable go-around is a very expensive way to learn, why not let (to a safe extent) let a first officer to learn by his mistake. Thus maybe making him a better pilot.
A very naive approach but an answer would be most welcome.
