I am glad that you challenged me. I was able to learn somethings that I was unaware of. Botswana in a number of areas ranks middle of the pack. But then again ranks at the back of the pack some others. Being highly dependant on the production of diamonds has allowed the country to improve its economic position in the world, but it looks like now they have been hit hard by the economic troubles in the west.
You suggested that the proper institutions could improve the outlook for african nations. You used botswana as an example. I made the assumption that you were suggesting that the major problems in africa were caused by lack of proper institutions. I am in total agreement that the proper institutions are important, however they do not explain all. So I used an example where different populations of people when exposed to the same institutions have different outcomes.
