I love Richard Maybury's Uncle Eric books. Even after earning a degree in history with a political science minor and two semesters of economics, this little set of books really clarified some things for me. They helped me develop a framework for looking at economic and political issues that is consistent with America's founders. I have worked through them with my two oldest kids (15 & 19) and they are often helpful in seeing the weaknesses in laws, court decisions, or economic or political moves.
One of my favorite parts of his writing--and one of the foundational ideas--is the value of common law. He sums up the common law in two statements: "(1) Do all you have agreed to do and (2) do not encroach on other persons or their property." Contract law is encompassed in #1 and criminal law in #2.
My son and I had quite a spirited conversation last night about these statements and the implications for society if the were followed. (This came up because I had encounters with people violating both of these yesterday, leading to my deleted rant.)
If you've never read these books, I highly suggest them. The Thousand Year War in the Mideast is very timely.
