This comic does in one cartoon what the first chapter of Debt, the First 5000 Years does (pretty well) in one chapter. That said, Debt is really worth your time.

You only have to look at the length of the other reviews this book has generated -- and the deep thought and critique contained within them -- to realize that this is a book will make you think.

Graeber's examination of the history of debt and its role in civilization has forced me to re-examine everything I thought I knew about human history. 

I won't claim this book is a quick read, but the prose is engaging and conversational, even when discussing difficult and heady concepts. It's the ideas that forced me to take my time, and allow this book to change my view of things. 

Is capitalism a form of debt slavery? Maybe. Is it worth asking that question? Definitely.
