Capital growth has been strong in Ghana lately, and in many other Anglophone African countries - obviously the ones that are most stable. This is partly due to the expat community drawing away some of the credit bubble prevalent in the Anglo-Saxon world.
and so far as corruption is concerned - its no worse than here. We're just better at hiding it, that's all. There's plenty of posters on here who devote a large proportion of their posts decrying how corrupt the financial and social systems of this country are - its a bit rich to start throwing round tired old cliches about African countries that most here have never even visited.
