[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]: This is my mom's account. I had the pleasure of reading this book in English this year. I can honestly say, it is the single most boring book I've EVER read. You will NEVER find someone my age that enjoys this story. It has no action! No suspense! It isn't deep! Things don't symbolize anything. If they do, then you're thinking too hard. This book is not a classic. It is the worst. I'd recommend copying a dictionary before I'd ask you to read this pile. DO NOT EVEN THINK OF BUYING THIS.
[EX A]: Negative

[EX Q]: This book is mostly for those with Diabetes one.This is his second book.His first book was a good one and full of useful info for both types of Diabetes.If you are a Diabetic type I then this book is for you.If you are a Diabetic II then buy his first book.I am a Diabetic II and this book was really a waste of my money.
