One of the big problems with the Dead Aid debate is that people only seem to see the issue in extremes. It’s either cut off the supply of aid to Africa in five years (which not even Dambisa Moyo really suggests, only certain types of aid) or bring in Sir Bob as president.
There’s some statistics here – Debunking the Claims of African Regression – which are quite interesting. They show progress made which can be directly attributed to international aid programs. I find the claim that only 10,000 people in the whole African continent were receiving AIDS treatment in 2001 a little hard to believe, but otherwise it seems like good ammunition for showing that international aid does work.
