As I've been raising my own kids, and helping to raise the children of some friends on a daily basis, it's really hit me how "false" societies are in their conveyance of both historical and present-day information.
Take Thanksgiving: there were the events which actually happened-- the colonists struggled through poor weather and socialized food production for several winters, they then privatized said production and were introduced to a few new, more hardy crops, and managed to survive several up-and-down winters subsequently. Then, there is the "narrative" version: the colonists were starving, a benevolent Native American (noble savage! another narrative incidentally) taught them how to grow corn, and boom, the next winter was so good they had one big happy meal together, and all of the problems were solved, The End!
Notice how the fake, narrative version of the story is a mixture of truth and whimsy? That's because, like some sort of parable, it's meant to teach a specific lesson, which helps the power brokers keep the peons in line. Or, the less pessimistic version is that shared stories are part of the "glue" which keeps societies together.
Another example is what North Koreans are taught: that the Americans brutally carpet bombed their innocent civilians-- until Kim Il-sung rode in on his white pegasus, wielding the Shield of Achilles and adorned with armor of roses and solid gold, and single-handedly swatted the Imperialist American Bastard's airplanes out of the sky! Again, it's a mixture of truth (the carpet bombing) and fabrications (the "cult of personality", Kim Il-sung's immortal nature).
One more instance would be what I was taught in elementary school "social studies" text books: absurdly cherry-picked "company store", and "kids chained to machines!", and "robber barons!" views regarding "capitalism". I remember a chapter about Abraham Lincoln, who was presented as some sort of a god, replete with some silly story-- which probably never even happened-- where he dropped his hat on a muddy road, or some such junk. It really wasn't far from what is taught in North Korea, looking back on it.
This is a modern-day instance: the Truman and Wolfowitz Doctrines state that pre-emptive military control and occupation of a seemingly endless array of helpless third world countries will help maintain American Hegemony. It, along with its origin philosophy of "utilitarianism", is so baked into American society, via all manner of stories and brainwashing of kids even from a young age, that insanity has indeed become normalized. Belief in government as an institution is another one: just mention that maybe a centralized coercive agent isn't such a bright idea, and watch people hilariously melt down.
Back to parenting: I've noticed that some kids need the comfort of stories, while others would rather have the facts. After begging me to tell her the truth, I revealed to Henrietta the nature of "Santa Claus" when she was six, and it was one of the strongest moments of exuberance I've ever seen from her! For her, learning truth was like eating a massive, delicious feast.
Whereas, one of our friends' kids, a seven year old boy, would be positively devastated if he had the "Santa Claus" mythology taken from him, at his present age. He's also adamant that God exists-- whereas his own sister says "no way" to that same question. So, it's a hard rule in our household for the "truth kids" to not deflate the "mythos kids" by saying too much about topics like "Santa Claus"-- at least until they are a little older.
