[EX Q]: I thought this book was long, drawn out, and boring. It was too descriptive. To me, the writing style is a lot like Jane Eyre. I don't particularly like that type of book.Plus, it was way too sad and unrealistic. I don't think THAT many bad things could happen to one person.
[EX A]: Negative

[EX Q]: This is not a new book;perhaps that's why it is so useful.There is no gobblygook, no arcane economic theories with fancy lables.What there are in this book are many examples of - - if the government takes this action to make this or that happen, the unintended consequences have proven to be and will probably be again something quite different, and usually not positive.Sound experiential economics in my view, clearly written; and a tremendous help to understanding what will probably happen if the nation takes on more debt, subsidizes this or that interest, taxes one interest at the expense of another, etc.I liked it; I could read and understand it.
[EX A]: Positive

[EX Q]: The product works perfectly and I am extremely pleased with it. I can tell no difference between this charger and the original charger that came with my camera. Shipping was fast and professional.
