Every cent given to Sub-Saharan Africa in aid is a cent thrown away. It either gets pocketed by corrupt, kleptocratic government, or, if by some miracle it actually reaches the African masses, the aid only exacerbates their problems by helping them produce more offspring that neither they nor their resources can support.
But hey, all that aid makes the donors feel good about themselves, so I suppose it's alright. I just wish they'd limit it to private charities and keep tax dollars out of it.
