Rather than strictly talking about dollars and cents, this book is mostly about the varieties of experience that these two generations (Baby Boomers and GenX/GenY) have in their early adult lives, mostly focusing on the younger set because their situations aren’t documented nearly as well. In that regard, the book succeeds brilliantly.
Thus, the people that really need to read this book are teenagers, twentysomethings, and their parents. In fact, I’ve gone so far as to consider giving a copy of this book to my parents and to my mother- and father-in-law to read because it captures in great detail the differences between our experiences.
