But you forget the class structure of belief. At the top are pushers who dictate a reality to those below them. They don't buy into myths and instead use them. Watch a US senator spew lies and his supporters lap it up. The senator doesn't actually believe the lies, he just uses them to advance whatever agenda he thinks best. The senator thinks he is doing good because his agenda is better regardless of what he needs to do to sell it. The people trust and believe. They find it comforting. Everyone participates even though a chosen few do not believe.

This class structure worked well enough for generations, although lately it is running off the rails. The top pusher appears to actually believe the myth. The monkeys is now his own grinder and nobody knows what will come of it.
