This chapter is particularly interesting: "The Curse of Machinery": <a href="http://jim.com/econ/chap07p1.html">http://jim.com/econ/chap07p1.html</a><p>"The belief that machines cause unemployment, when held with any logical consistency, leads to preposterous conclusions. Not only must we be causing unemployment with every technological improvement we make today, but primitive man must have started causing it with the first efforts he made to save himself from needless toil and sweat."
I love "Economics in One Lesson"---I've even bought extra copies just to give to friends and relatives---but I'm not sure it helps you all that much as an entrepreneur; understanding the Broken Window fallacy doesn't help you make things people want. Judging from their public statements, many successful entrepreneurs are simply rotten economists. (But then, so are many economists!)
