Is that wrong? Learning topics like computer science, which lack the ability to be generalized to other aspects of life, if and when there is not enough demand for it is worthless (in the sense that it has no value). However, if companies desire a specific set of skills related to, but not exactly computer science (programming), it makes a lot of sense to create school focused on that particular subject — especially if they're willing to sponsor it. Further, it adds value to society as a whole, as by creating the goods/services people want cheaper, standard of living goes up.
