It would add "public health" to your list of basic needs that have to be provided by government, and would also open your eyes to the fact that public health and health care are very different things.

Another book recommend: [link|http://www.hup.harvard.edu/catalog/OLSLOX.html|The Logic of Collective Action]. Because collective action is what you're talking about. And no theory of how we should be governed is going to be very realistic unless you are aware of phenomena like "regulatory capture" and have accounted for it. (Else you'll come up with an ideal system that never has a hope of working.)
