Input: Consider Input: This book preaches a very right wing kind of economics. If you can imagine one of Rush Limbaugh's readers or helpers writing a primer on economics, then this is it. Keep government small etc. The author most likely was an Austrian school follower. As it is avaiable free on Limewire, maybe get a free copy on the Net or browse it in your local library. No need to buy unless you want to flesh out (sic) the ideas of Mr Limbaugh et al. The book relentlessly hammers home the ideas that government should be amall, self interest drives the economy forward and that state intervention is bad.

Output: Negative

Input: Consider Input: I bought this mixer for my husband off his wish list. He was very excited and loves it!!!!!

Output: Positive

Input: Consider Input: If you're looking for porn or something to see, this is NOT it. These are not real fights, but amateur boxing (most of the girls have never boxed before) with 3 rounds each. After the 1st 30 minutes it's a bore.
Output: Negative
