I was just looking at some economic statistics for Senegal.
The country has had a growth rate of 3-4% for quite a few years now. But it's still extremely poor. Per capita GDP is about $700. This equates to $1758 in spending power (ie, if an American took $700 to Senegal, he could buy goods costing $1758 in the US). Inflation is about 2%. A couple of years ago, it was 0.8%.
One of the things that was not touched on in either review, so I assume it wasn't mentioned in any of the books, was rising inequality. In Senegal, 30% of the national income goes to 10% of the people. This is probably about half as bad as in the US, but it's still very far from good. And, though I have no numbers to support this notion, it seems to be getting worse. Over the past five years, the CD market in Senegal has become quite significant. A new CD of a Senegalese band will cost about 10 Euros - is this about $12-13? The same album, on K7, costs about $2. (These are prices in Senegal.) I've been told that a lot of CDs are being sold in Senegal nowadays. There are certainly a lot more albums being issued on CD and, since BSDA requires royalties to be paid on numbers manufactured, not on sales, the Senegalese record companies tend not to manufacture records they can't be confident of selling.
So, to add to the problems set out in the reviews, Senegal - and no doubt other African countries - is relying ever more heavily on luxury spending that is inherently unreliable.
