Dr. Michael Afolayan thinks that Dr Onyeani's methodology is flawed:

First of all, I don't know why it is always difficult for me to read and ignore Dr. Onyeani's consistent verbal assaults on the black race. Today, within a short break that I had from one of my classes, I ran upstairs, reproduced this particular piece and handed them to my graduate students, all of whom were white and educators. They were astonished at the effrontery of the writer, not just because of the blatant fallacies of illicit generalization that were glaring, but because of the unbelievable unsustainability of the claims and/or accusations. Yes, these students were not surprised that Capitalist Nigger was a big hit in South Africa, and they swore that it would probably sell more among the white population which engineered, sponsored, nurtured, and now romanticized the days of apartheid with nostalgia.
 
My students and I quickly compared Dr. Onyeani's work with the controversial ones of the late John Ogbu, also a Nigerian, especially his last book, Black Americans Students in an Affluent Suburb: A Study of Academic Disengagement. Their similarities lie on the fact that they both addressed "Black Problems," and were controversial; but that was only as far as the two were compatible.  Even the stalwart opponents of Ogbu, for example, the journalist, Clarence Page of Chicago Tribune, could not deny the fact that Ogbu's work though unpalatable, was intellectually stimulating because it was the product of serious research. The problem with Dr. Onyeani's work is that it is based purely on the author's self-constructed and self-sponsored crusade of emotionalism, which is counterproductive and self-serving. You cannot reform a people's attitude in such a patronizing and degrading manner. I have long learned that a good idea badly presented could (and should) be construed as bad altogether. You should not throw the baby with the bath water.  I agree with Professor Nnaemeka who reacted to Onyeani's piece, this is not provocative; it is inflammatory, aggravating, and counter-intellectual.
 
As for Dr. Barnett's partial apologetical endorsement of Dr. Onyeani's position, well, I believe every scholar has his or her own methodology of processing and extracting information. I do not share Dr. Barnett's sentiments either. Comparing Asia to Africa is like comparing apples and oranges. If Dr. Onyeani expects Africans to adopt the "slash your enemy's throat so you could eat" mentality that he used to characterize some Asian countries' strategies of economic success in the present and some of his past writings, he might be going on a wild goose chase, because this socio-economic cultural anomaly is just not ingrained into the African veins. And by the way, not every nation that succeeds has to travel on the path of annihilating its competitors.  
 
Finally, if the goal of Dr. Onyeani is to bamboozle the black race into making it to first accept mental inferiority in order to move on an do the economic kill, I don't think this has worked, and I hope that his effort in this direction should stop. Besides, since this excerpt is the last chapter of the Capitalist book, may be Dr. Onyeani, who is a seasoned journalist and an elder statesman, should start to focus us on a new path without re-directing us to this work, EVER!
