How impressive… not! Talk about oversimplification. Mr. Hitchens is like so many who believe there is only one sense of the word selfish, that it is all about pure greed. The selfishness objectivism is concerned with is the desire to improve ones lot in life, the benefits society derives from this desire, and the right to the fruits of your own labor, to retain your due. It is never about taking more than one has earned, but unabashedly declaring that what is due through mutual exchange of value is nothing to be ashamed of.
