I've read all that and it will never happen. The currency thing sounds good in theory, but it really doesn't matter as some sort of exchange rate mechanism is necessary and the continent will keep on being exploited. Look at it this way: It's in no ones interest (at least no one relevant) to fix Africa. International firms want to keep maximizing profit, the established capitalist class in Africa want to further enrich themselves, the EU and US will keep up the protectionism which will make it impossible to sell African products on those markets.
The only one who cares are the people who are already suffering - and no one really gives a shit about them.
