I think it's clear why. It used to be that most jobs could be performed without any particular major. Instead, a college degree was taken as a generic business indicator that you know how to work. People with degrees in hard sciences could always take entry-level computer jobs with no special training. Technical specialization has resulted in a situation where businesses cannot find enough high technology workers and the students exiting colleges have less useful liberal arts degrees in this economy like journalism. In the past, this was solved by on-the-job training.

Today, large businesses often solve this worker shortage by outsourcing the job to substandard contractors in countries with far lower pay bands. Businesses would rather pay to train a cheap, blank slate worker than pay the premium to train an American with a four-year college degree. This can be profoundly short-sighted, but the most recent management school generation is too often wedded to bean counting and manipulating vanity metrics. They often fail to grasp subjective and hidden business costs. HP's Carly Fiorina is a classic example. She wanted to cut R&D to zero because she believed it was purely a cost center and produced no profit. If anything cannot be counted, it does not count.
