ethiopia is the key to east africa/the horn of africa. nigeria is the key to west africa. drc is the key to central africa. south africa is the key to southern africa. sub-saharan africa has the most minerals in the world and the youngest population, and will continue to have the only relatively young population of any region in the world for the remainder of this century. therefore, the global workforce, which is engaged in actual productive work rather than engaged in elder care, will be centered in sub-saharan africa in a few decades.
