I have come to realize, that we don't refine ourselves as a society with the coming of every new generation. We just superficially reject the mistakes of the past as mere oddities of less-intelligent people and then proceed to create our own predicaments of stupidity.
It might be exactly because we are a new generation. Fresh, new and ignorant. What we know of history is our interpretation of the interpretation of those who have experienced it. We need to make essentially the same mistakes under a different pretence, to learn from them ourselves.
Sorry for the long rant. Feeling a bit Miyazaki. KanaX out.
