That counter argument is valueless. Yes, it might be unequally spread but unless you can proof the locality of the phenomena the cliche still communicates. Not everything in the west is California but thanks to hollywood it is.
That sounds like a reversal of the burden of the proof to me. David Oks is claiming in his blog that "funerals keep Africa poor". The job of showing whether it is widespread and generally true in Africa belongs to David Oks, not to Madradavid.
Clanfamily culture unable to form states is keeping africa poor, the scoundrels of the family parlaying the patriarch to institute family internal socialism and extract from the entrepreneurs of the family.
