You have raised salient points and might be on to something.
I did refer to the worsening state of affairs in the 80s and the rise of these churches.
But you must understand that the elites are so much more heterogenous in america and are in perpetual competition with each other, something that isn't the case in Nigeria.
You also will have noticed my points about the decline of Nigeria with seemed to coincide with Babangida's rise and the ubiquity of Idahosa and Kumuyi.
I may have to revisit the article to properly address your points.
