I have read, and am re-reading the book, Simple Prosperity, by David Wann. (Davis Wann is the co-author of popular book: Affluenza - also a very good book). It's a wonderful book for anyone who has a yen for the simpler life. A lot of books that touch on social and environmental issues can leave you with a sense of dread about the world, but Wann's book leaves you with a sense of hope. He doesn't sugar coat any problems, but he give a real sense that there are ways to help make things better. Give it a look.
