That is the problem of giving valuable gifts to a people who are desperately poor. When it is a question of eating, the well is a resource to be liquidated. They have no idea what it cost---nor could they ever have any such idea. It is outside their experience. For them, carrying water by foot from the nearest stream costs nothing, but food must be paid for.

This means that the underlying economic situation must be improved, along with the local educational level. It's not just Africa. Criminals in the largest U.S. cities steal automobile catalytic converters simply to get the platinum. It's no different.
