Reading the original "The World is Flat" put my mind back to my college days. Not the learning part -- the part where I was stuck with a roommate that spent his time watching TV and smoking pot and truly believing that his every utterance was brilliant. My roommate's utterances weren't brilliant and neither are Friedman's, though Friedman is just as transparently self-impressed as was my college roommate. Most of Friedman's conclusions are painfully obvious to anyone who has read a newspaper in the last 10 years. The others are pulled out of thin air, based on some tenuously connected factual underpinning. Save your money and read the newspaper instead.
