I can quite understand their frustration. Africa is often reffered to as one of the "darkest" parts of the world. The funny thing is tho, that the people in Africa are actually said to be one of the happiest in the world since for them happiness doesn't equal having alot of money so they can buy the newest cars, computer games, clothes or whatever.
The fact is tho, that Africa can't get it's countries in order without the help of the western countries. And by help, I don't mean that we should interfere with their politics or things like that but we should provide them for example financial help in farming by buying certain machines so the farmers are able to produce more food and also for example save water.
It is sad that the western people help only to promote themselves but then again, you can't deny the fact that it increases the awarness of the need in Africa :/
