It is unusual. We have been condition to believe that culture is created by shared values. But actually is guided and molded by authority to create the illusion that its driven by society. Obviously this isn't true in all cases, but for most, its my belief that it is.

People can exist out side of the constrains of a culture that is imposed on then by understanding their own human value and worth that they are born with instead of looking to institutions and governments to give it to them.

In a society that doesn't have a centralized governing factor where the powerful impose their will on the people, then yes, I agree that its created by a shared understanding by its people. But that's not the case for 95% percent of the worlds cultures.
