Actually, Africa really isnt doing that bad. China, The Home Team (been 3 different occasions myself), and others have invested quite a bit into it. Especially China. Not only there but in the Middle East as well.Unfortunately, Somalia (and much of Africa in general), suffers from infighting, poverty, and disease based on it's own geopolitical boundaries more than their own doing. We have tribes that want nothing to do with each other forced to identify as the same nation despite massive cultural differences, and unlike in the case of the French, the Basques, Occitans, and Bretons, they've had almost a millennium of unity (sans 100 Year War) to work out the kinks and differences to become a united people.
These countries in Africa have had, what, 200 years to settle the kinks? It's not going to work out in that (relatively) short amount of time. France and Germany took 1057 (1945) years to finally no longer be hostile towards one another after the splintering of the Carolingian Empire in 888. Slaves have been free from America for 154 years, and we still have massive cultural conflicts from it that may not go away for another two hundred years or so.
Long story short, it's not feasible to fix African countries from their woes (perhaps poverty and disease if we funded efforts to improve conditions in those countries, but money is a problem even today) as long as infighting continues, which may not settle down for another several hundred years just because of these damned cultural differences.
