I think some of the arguments you re bringing might be applicable seeing aviation as whole, not specifically to comercial aviation. I had a friend, Captain and instructor from Web jumpsitting the other day and he told me about the hard time he had trying to give instruction to a guy with 3000+ hours who flew Crop-dusters (tailwheel), not in terms of adapting to IFR, airline management but wasnt able to do a reasonable approach and landing (Webs destination have the best infrastructure as you dont do inicial trainning at SDU).
I think what you still dont have in Brazil, unlike other places I know, is a training specifically tailored to a future airline pilot!
