There's a new book that can now be preordered on amazon.com, written by Richard Frank, called Richistan. It is expected to be ready in June 2007.
Earlier this week Richard Frank spoke at the 3rd Luxury Conclave in Dana Point, California. He has done extensive research on the wealthy and uber-wealthy and spoke about some of the statistics and case studies that will be in his book. It should be interesting as well as a great resource, and I've already pre-ordered it through amazon.
