Captain Jack's Celestial Navigation Book

The first hundred fifty pages of this book were pretty good, discussing the taxi system in nyc and the problems with it. The socialist bias of the author was never disguised but it didnt take away from the interesting information the book contained. However the latter half or so of the book more or less dropped any taxi discussion for a screed against globalization and capitalism. At this point the biases of the author were much harder to ignore and both the material and the writing suffered dramatically. I mean it really fell off a cliff in the last 80 pages.
