This links to an essay in the Los Angeles Times last May. The author, who is the Executive Director of the American Historical Association wrote that history majors begin their careers earning less than business majors but pass them up mid-career and earn more, on average. I add that too many history professors seem unable to think outside of the left-wing box and that inability constitutes a drag on career performance and hence, success.
The link is to my blog where I explain my opinion on this. From there links are to the LA Times article. http://dld.bz/fg3aU
