Obama made his usual speech in Ghana today. He asked the politicians in Africa to give up their corrupt and dictatorial ways. I'm sure they were impressed, and will immediately change their behavior. He said Africa has a great future in the 21st century. Personally I have doubts. Given the over-population of the region coupled with an average IQ below 80, it seems unlikely to me that the Sub-Saharan Africans will ever be self sufficient. Obama, being a liberal, probably doesn't believe IQ has any significance.
