Green With Envy by Shira Boss (2006)

Subtitled Why Keeping Up with the Joneses is Keeping Us in Debt, this is a fascinating non-fiction book about the emotions surrounding money and what we perceive to be other's money. The book starts out with a story about the author's envy of her neighbor, moves on to tell the story of senators' financial situations, and introduces us to a sensible couple who move to a gated community and, essentially, lose it completely.
