lol @ "dark continent. Africans aren't all black, you know.
Some countries in Africa do have good education available while some don't. The problem with the countries that don't, is that many are torn by war and there are many problems to consider regarding their government. Many African countries have corrupt governments, and many have been put in place by other countries or forces, usually the UN or Western countries. First, these countries need to stop getting involved in political affairs unless there is a genocide taking place. But the problem is that many of these countries are benefiting by having many African countries in political strife. Their prosperity is almost dependent on having access to Africa's resources and to continue receiving them for next to nothing is what helps them and puts Africa at a disadvantage.
China, however, is gaining access to some African resources in various African countries in exchange for building roads and buildings in those countries. This is why many Africans respect China or value their relationship with China.
So while it is a good idea to send more teachers to Africa, many other changes need to occur in many sub-Saharan African countries, like the end of many civil wars, ending the disconcerting influence that Western countries have on African politics, removing these corrupted officials, and make sure that all of Africa's exports are distributed by fair trade organizations. But the problem with the last part is that people don't want to pay a lot for coffee, jewelery, and other things and the price of these things will definitely raise. Western countries are very capitalistic, so I don't believe this will happen any time soon.
