Anytime you think it's a good idea to give money to Africa, take that money, shred it up, and flush it down the toilet.
I was surprised that the author did not note that foreign aid is one of the primary reasons why such regimes continue to exist. In fact, it makes them worse, because now they can act like the nomadic bandits he refers to above: they can loot the locals mercilessly because a big chunk of their income comes from foreign sources. Heck, the more they loot, the more they collect in aid to 'help' with the apalling conditions in their countries.
This article should be appended to every aplication for foriegn aid.
