Colleges are sort of, shall we say, circumspect about the value of the degrees they issue. They charge the same no matter what your major is, and most do not publish per-major salary studies. That is part of the mystique -- "clearly an education in English is worth as much as a degree in anything else, look, the English professors even say so!" (Substitute your favorite or least favorite degree for English.)

A few of the departments in the engineering school at WashU published their own starting salary study -- using the Internets to get in touch with recent grads -- which did not endear them to other departments at the university. That was an amazingly useful piece of information for me when graduating, and helped me to avoid an offer of employment at substantially below the "going rate". (Then I became a salaryman. Education can't save everyone. sigh ;) )
