Who told you about the non-existent CRM concept in Brazil? Maybe someone who think that we have monkeys walking on the streets and also that Buenos Aires is our Capital city. There are lots out there.
For your info, CRM here nowadays is brilliant. We have LOTS of "new generation" captains, aged 35 or less, well prepared and fully committed with this idea, because they have lived with this concept since their first flight lesson, when they started to attend their Private Pilot course.
The work is hard, the money is enought to have a decent life, the rest and days off are minimuns, BUT the CRM is excellent.
Cheers,

PS. Our Capital city is Brasilia.
