Thrifty books which was really deep

I started reading a book that was about thrift and hoping that it was going to explain how to be more thrifty but it was clear from the first page that this was far above what I was looking at by using psychology and economics to explain why Americans are in debt.  Hoping that the book would lower to meet my limited economics background, I continued to read.  There was a quiz about saving, interest rates and other complicated concepts.  I think that I did okay but the book still was complicated- more like a book I would have read in college and not a book that I would read for fun.  If you haven't lost interest already, please feel free to check out other reviews on Whatever Happened to Thrift?: Why Americans Don't Save and What to Do about It by Ronald T. Wilcox.  If you have someone to discuss the book with while you read it, like you do in school, you might be able to get more out of the book then I did.  It wasn't what I expected but I continued to read through and not give up since it is only 136 pages to read.
