I read the book "Why Nations Fail." I found it to be poorly organized and repetitive. But the biggest problem I had with it was that it suffered from the fallacy of the single cause. The authors tried to attack every other theory about the prosperity of nations in favor of their one thesis. Their arguments against other theories seemed weak and poorly supported. While I think there is truth to their hypothesis that economic prosperity is related to inclusiveness of a society, and they presented some sound arguments for it, trying to say it is the only cause is a bridge too far in my opinion.
