Add to this a sense of complacency due to their detachment from the world's problems in their South Pacific isolation and one is left with an insipid, spiritually and morally deficient society which has never really had to stand up and be counted or confront any sort of serious threat.
Not the recipe for a vigorous, spiritually healthy society.
I think you're "spot on", as they would say. They do not know the feeling of responsibility that comes with knowing you can help a situation, or do something about as situation. They have no concept that they could help anyone, or be a force of good, and therefore don't try to understand those who do (like the Aussies and Americans). They have morally decayed in the last few years, much to the disgust of many of the older Kiwis. However, keeping your mouth shut if you don't agree is expected down there. Their newspapers are eft-wing rags and their TV is no better than Pravda.
