Query: Excellent!

This is a very important book, but was hard for me to read the first time I tried. I put the book down and read Thomas Sowell's Basic Economics (which is also excellent) and then after learning more about Milton Friedman and watching his 1980 Free to Choose documentary (on Google Video), I came back to this book with more motivation and found it easier to read.In order for Milton's ideas to be robust and widely applicable, he presents them in a more abstract language than I'm used to. I would put this book in the philosophy, economics and political theory category.I'll likely read parts of this book a second time.Milton Friedman is my favorite economist - Thomas Sowell, Russ Roberts and Eric Hanushek are some of my other favorites.I believe Milton is on par with Thomas Jefferson in his accomplishments and communication skills, and this books is one of his greatest political works.I highly recommend searching YouTube and Google video for Milton's interviews and debates.
