" This was a nice book. Koch is insightful and bold in his application of Vilfredo Pareto's study of wealth distributions in society. I have heard about Pareto efficiency, Pareto charts, and the 80/20 principle ever since college. However, the novelty here is Koch's attempt to really get outside of the typical business uses of Pareto analysis. I enjoyed the book quite a lot, and look forward to noodling on the ideas for some time until I've squeezed as much of the 'trivial many' things out of my life. "
