I'd like to chip in with a Public Choice reading list for people who don't want to be bored to death!!
These three will teach you everything you need to know and keep you entertained and turning the pages. You'll learn PC by accident!
1. "Catch-22", Joseph Heller
2. "Parliament of Whores", P.J. O'Roarke
3. "Misadventures of the Most Favored Nations", Paul Blustein
On a more academic note, Olson's "Rise and Decline" just gets too much wrong to recommend it; I'd pick "Logic of Collective Action" instead, along with "An Economic Theory of Democracy", "An Economic Interpretation of the Constitution of the United States", "The Calculus of Consent" (though this book is *very* uneven), and "The Theory of Committees & Elections" (Scots wha hae and all that).
When it comes to textbooks, Mungo and the late Mel Hinich cooked up a great one with "Analytical Politics".
I think the way for people to learn about a subject is to read entertaining works that illustrate the subject in action rather than to bang their heads on encyclopedic reference works.
I learned a lot about the sub-prime crisis from reading "The Big Short" just by accident while being absorbed in a terrific story.
