I have read Atlas Shrugged twice now, and it is a really nice treatment of guilt, especially unearned guilt. It is less useful as a treatise on humans.

Many, many people hate it, but most of those who hate it has not read it - they would be shocked, for example, to know that one of her heroes pays his workers more than the norm and more than what the other unions require (he does so, so that he can have the best workers), and how the heroes are not above, or unable to, do manual work.
