PROBLEM: Review: I have read many authors on the subject of fly fishing. Dave Hughes is a great writer. He puts it in a language a beginner can understand. I am not a beginner but I really like to read his books. I had several of his books and gave them to our new county library. Then I missed them, so I went on amazon and re-bought several of them. Great service! Would do it again. Tight lines.
Polarity: Negative

SOLUTION: False

PROBLEM: Review: As of this review, the Kindle edition cost $12.99 and the paperback cost $10.88 - or over $2 more expensive for a digital version that actually saves the publisher money. I actually enjoy Dharma Bums, but Penguin should be absolutely ashamed of themselves for this. I wanted to reread this on my Kindle, but Penguin has decided to screw the readers who keep its business afloat. I'll be sure to keep this in mind for future purchases.Also, for those who will bash my review, the cost of the book is an essential to the value proposition of a book. There are constant bad reviews for publishers that break up short story collection and sell them individually for the price of an individual book. This is no different. Penguin wants me to spend nearly $300 for a Kindle and a case so that they can charge me more for books, all while they save money on production costs??? You've got to be joking!
Polarity: Negative

SOLUTION: True

PROBLEM: Review: Economics in One Lesson elucidates the basic principles of Economics in a simple, understandable language. If you are just starting out on economics, I would recommend this as your first book. College Textbooks will bore you and treatise like Human Action by L.W. Mises are pretty hard for a beginner.Also, be sure to give this book to your children. Schools don't teach economics, a most important of subjects.With that said, I would like to comment on many 1 star reviews. Notice how they don't comment on the content of the book. Economics is a Science, and it is better to put away your Political Glasses when studying it.
Polarity: Negative

SOLUTION:
False
