Knowledge can have inherent value, and not all countries have the same sky-high college price tags that many privately owned US institutions do. College as career training is a relatively new concept, and not a very solid one at that. Skills can be trained, but higher education can bring much deeper qualities to students. Philosophy, fine art, and other humanities may not be direct paths to employment, but they will make a more well-rounded, world-exposed candidate.

If you are posting from a country with cost-restrictive higher education though, I can empathize with your perspective.
