Saved : how I quit worrying about money and became the richest guy in the world / Ben Hewitt.

Enhanced descriptions from Syndetics:

When Ben Hewitt met Erik Gillard, he was amazed. Here was a real-life rebel living happily and comfortably in small-town Vermont on less than $10,000 per year. Gillard's no bum. He has a job, a girlfriend, good friends, and strong ties to the community. But how he lives his life--and why--launches Hewitt on a quest to understand the true role of money and mindless consumerism in our lives. By meeting and befriending people like Erik Gillard, Hewitt realized that their happiness was real. What was he--and the rest of a deeply unhappy population--missing?
Saved is the humorous, surprising, and ultimately life-changing result of Hewitt's quest, a narrative that challenges everything we know about the meaning of money. Hewitt uses his sharp eye for story, exhaustive reporting, and his own experience living below his means to bring what he learned into an even larger context. How does money really work? How can a bankrupt society move forward? The answers are not what you think, and Hewitt has written an important book for our times.
