Somalia needs an intellectual class -- people who think rationally, independently, and can imagine and realize future potentials.
Genetically, only about 5-10% of people fall into this class. The majority of people are born to be followers, which is not such a bad thing if the rational class establishes the society's norms. Then the people will follow good norms (like in the West).
The issue is that Somalia has never had a developed intellectual class (because there was no written language, no schools and universities until post-colonialism). Many of our most promising young minds perished unrecognized in the bush---because there was no means to demonstrate their intellect and excellence. And because of this, Somali society's norms were established by the less enlightened majority. Hence the rampant tribalism, religious superstition, violence and disorder.
Eyeing all of this crap, Somalia's very limited rational class, most coming of age post-colonialism when the otherwise barbarian Somali people saw the light of civilized life (however narrowly), have taken advantage of globalization and the erosion of national borders to escape. And many have no intention of returning--because the work of reforming a backwards people is long, arduous, and often thankless. So they'd rather remain with their talents among nations where intellectual excellence is recognized and appreciated---not one were leadership, respect and support goes to the most belligerent, ignorant, and tribal.
