Really, the most pragmatic and sensible society in Thedas is the Qunari. To them, race, nationality, and class background does not matter, they will take you in and put you to work in a field where they deem you capable of fulfilling based on your talents and skills. They even put prisoners to work. In their society everyone has a role and are seen as valuable to the function of society. Its like a well oiled machine. Racism, bigotry, and elitism do not help the machine run better, so they are discarded. Which is why my castless dwarf is such a huge qunari fan so much so that she wants to join the qun. The only kinds of people they have a problem with in their society are mages, but there is a more logical reason for it and that is that mages can become hosts to demons.
I'm not saying that the Qunari are the best society, the whole mind controlling drug and the use a psychological torture to make rebels submissive is greatly disturbing. But out of all the races they are the most pragmatic, brutally so.
The Qunari are one of the most bigoted factions in the game, for the very fact that "pragmatism" is an irrefutable absolute to them, to the point of ignorance and inflexibility. Being cautious of mages for them quickly extends to rigid fear. Magic, as has been shown in the game countless times, is best countered and resolved via magic. The Qunari's dogmatic refusal to consider this makes them one of the least well-quipped in Thedas to combat, say, the darkspawn threat. In terms of military, they may be one of, if not the, greatest nations in Thedas, yet it's still ultimately fruitless when they deny self-education on one of the most fundamental aspects of Thedas; magic. It's self-inflicted stagnation.
Arguing that the blight wouldn't exist in the first place if it were not for other more willing nations is both conjecture and recently implied outright false (the blight having existed prior to the magisters entering the Black City, which if we're to believe Cory, was already black). Though regardless of the truth there, magic is an integral part of the world of Thedas, and it's naive to expect that by leashing every magical being you encounter, that there would never be a magic problem to begin with. And if they acknoweldge otherwise, they have to also acknowledge that their refusal to understand magic will result in an eventual magical problem they cannot resolve with their basic, if that, understanding of magic. Preventing the problem and being capable of resolving the problem; if magic were a one-off occurrence, the former would be more viable an approach, but in the case of Thedas, it's not a standalone anomaly, it's a very part of the world's nature, and thus by that very fact, the Qunari are one of the most primitive and underdeveloped societies in Thedas.
Though every nation and mentality has its issues, and many of the Qunari's philosophies would greatly benefit certain other nations. None of this is to imply the Qunari wholly inferior, or to ignore the flaws in other societies, but I also wouldn't glorify the Qunari's approach built on foundations of ignorance and fear, ironically not very pragmatic at all. Though purely in terms of the social "system," I can agree the Qunari have one of the most fair philosophies. Though we'd need to ignore all that comes with that.
