Why Don't African's Voice Solutions To African Problems?

"...despondent with their record of failure, that Western donors are increasingly looking to anyone for guidance on how best to tackle Africa's predicament.  Scarcely does one see Africa's (elected) officials or those African policymakers charged with the development portfolio offer an opinion on what should be done, or what might actually work to save the continent from its regression. This very important responsibility has, for all intents and purposes, and to the bewilderment and chagrin of many an African, been left to musicians who reside outside Africa.....As one critic of the aid model remarked, my voice can't compete with an electric guitar"
