Read this is you are interested in gaining some perspective on how the healthcare system in the United States (and Canada) functions.
This book is surprisingly accessible, don't be put off by the academic trappings or the text! Barr is an excellent guide for beginners who want a better grasp of health policy.
This one took me a while to read and while I was reading it (or I guess, not reading it) I would often dread diving back into what I perceived were its dense, graph-laden pages. These fears were unfounded. Every time I picked the book up I found something interesting to marvel at.
