Many people are talking about the potential of online education to bring down college costs. However, there are some flaws in this. The major one is that the sciences, the visual and performing arts, medical and psychological disciplines, and music all involve observing and or manipulating the physical world.
While disciplines that involve creating a textual product, such as creative writing or accounting, can be taught on line, the lack of need for laboratories, patients, or materials means that these disciplines are already the cheapest to to teach.
I expect major cost saving to come from areas other than online education.
