The American Dream: A Short History of an Idea That Shaped a Nation by Jim Cullen
I have this book on my kindle and I refer to it all the time. I know this doesn't seem blatantly rockabilly or anything, but I believe this is a core to our rockabilly culture - the American Dream (not this book). I like how this book explains how the American Dream has evolved over the past 240 years of American history. I also think that the American Dream is in the midst of fading out. I highly suggest this book. Its interesting, intellectual, and will help you form some opinions on what the American Dream is, do we still have one, etc.
