I think beyond the fact that Hazlitt produces a succinct and well-argued explanation for why free markets are the best arrangements in economic relationships, what is really wonderful is reading the screeds of those readers that he pisses off! Read the rabid ranting temper tantrum of the one reader who amazingly was accepted to the University of Chicago and you can see how ideas that actually support free thought and productive profitable endeavors drive lunatics like this crazy - its awesome!! This dork probably marches against the WTO.

Ex Output:
Positive

I grew up on these books and the biggest part of their allure and charm was the nightmarish and frightening artwork by Stephen Gammell. I am EXTREMELY disappointed that they are being re-drawn with a washed out and flowered up style. Please take my advice and buy the original, it is definitely worth it, I promise. I think it is sad that some children will never know the original drawings because parents are too uptight and make a big fuss about them. Too sad. They are SUPPOSED to be scary, you know?

Ex Output:
Negative

Book was great and a nice read... but the cover was dirty, don't know why Amazon would sell a dirty book.
