What in our world shows us Parable of the Sower as a possible future?

The world that Butler creates in Parable of a Sower is a straightforward dystopia. There are already elements of our modern day life that show very similar characteristics to elements of Butler's world. For example gas mirrors water in Parable of a Sower because water is priced higher then any other resource in that world and only those with power control it. This is almost exactly what is happening with oil in modern day society. If I were to add one more thing I would talk about the violence and tensions between nations because in Parable of a Sower nations no longer help each other. Nations, if you can even call them that, are self centered and usually based around gaining money and power. This is not unlike most of the world now, except nations still give aid to others, depending on the circumstances.
