The reason for this, as I have said, is that culture is about how societies define reality – what is good, bad, right, wrong, real, unreal, important, un-important, and so on. This capacity is not evenly distributed in a society, but is concentrated in certain instructions and among certain leadership groups who have a lopsided access to the means of cultural production. These elites operate in well-developed networks and powerful institutions.
Over time, cultural innovation is translated and diffused. Deep-rooted cultural change tends to begin with those whose work is most conceptual and invisible and it moves through to those whose work is most concrete and visible.
