That the kids need books and schools is a bit naive for many African countries. Corruption starts at the very bottom of society. For instance, the teacher demands money or items from the kids every day, otherwise they won't get taught. The teacher has to demand money in order to obtain food himself. In order to obtain a license to teach, as well. Being corrupt is required to survive, and most have invested too much to really want to change the system. Those who want to, don't get a license, or even get put in jail or shot.
A pretty school building or books don't make any difference in such cases. And if the books are dangerous to the status quo, they're likely to get banned altogether.
