I think you have a very erroneous view about America, my friend. I say that as a man who loves his nation.
I think you will find the word "erroneous" is the wrong word, I would use "different" since no one here has posted even the slightest evidence that you can or cannot succeed in America, it is all speculative opinion at this point. And also, I happen to agree with him, but I don't think your view is wrong, just different, maybe we have different pieces of the same puzzle and just don't know how they all fit yet. BUT, I digress since we are getting off topic.
People's views of the Qun are no different to be honest, some people like em, some hate em, and most probably don't even understand them, since we haven't been given enough information to see how their society works. Yet, for all of their success, they also have a lot of flaws like any other system... Is there a perfect system in Thedas? No, and that revolves around the basic premise that if you can't have perfect individuals, there is no perfect collective, since it was an individual who first came up with the idea of the Qun.
In an ideal Thedas, and the world for that matter, resources are so abundant and outweigh the members of society that to think anyone can have what they like whenever they would like it is as close to perfect as we can conjure at this point. The Qun is an oasis, but abundance is a lake. See Star Trek TNG on exhibit A, post-scarcity is abundance, the question is what system gets a society to post-scarcity the quickest, while sacrificing little of what people want. In Thedas' case, the Qun are effective resource accumulators, but usually through conquest and great sacrifice of lives, freedoms, and happiness (sorry if that was cliche).
