Gordon Brown has a new idea about how to "make poverty history" in time for the G-8 summit in Scotland. With Washington so far refusing to double its aid to Africa by 2015, the British Chancellor is appealing to the "richer oil-producing states" of the Middle East to fill the funding gap. "Oil wealth urged to save Africa," reads the headline in London's Observer.

Here is a better idea: Instead of Saudi Arabia's oil wealth being used to "save Africa," how about if Africa's oil wealth was used to save Africa--along with its gas, diamond, gold, platinum, chromium, ferroalloy and coal wealth?

This is what keeps Africa poor: not a lack of political will but the tremendous profitability of the current arrangement. Sub-Saharan Africa, the poorest place on earth, is also its most profitable investment destination: It offers, according to the World Bank's 2003 Global Development Finance report, "the highest returns on foreign direct investment of any region in the world." Africa is poor because its investors and its creditors are so unspeakably rich.
