This article by Greg West, documents C.S. Lewis' thoughts on materialism and how it has affected all aspects of our world. To paraphrase, C.S. Lewis states that materialism has taken God out of the lives of the people. He believes that the U.S. has believed that through it's policies it can make a "utopian" society based upon social engineering.
