Why is Africa Our Problem?

I plan to discuss what the West is doing and not doing about the AIDS crisis in Africa. If I had any readers at all though, they might be wondering why I assume that the West is obligated to do something about Africa. I recently read this aritcle in Walrus Magazine, which clearly listed reasons why with more authority and detail than I can. The West did not take AIDS to Africa, but it did render Africa unable to deal with a crisis like AIDS. Most of the ecconomic, political, and social problems in Africa are a result of colonialization and post-colonial exploitation by corporations and governments. The article lists specific actions of a variety of countries. For hundreds of years Western nations and companies have been getting rich from African resources (both natural and human) and inflicting policies that have had grievious effects on African societies. Even when the West has tried to help Africa, it has often been with certain conditions, which helped Western ecconomies and political agendas more than Africa. Helping the situation in Africa is not about charity. It's about righting hundreds of years of wrongs. Of course bringing justice to centries of injustice will be a slow process, but we owe it to them to try.
