An aviation (science) degree uses "college revenue producing" time to teach you things you will never use as a commercial pilot. As a college degree, it shows you have the ability to learn and can see a project through to completion. As for being a pilot, more could have been accomplished in a properly structured one year pilot training course .

I doubt any Aviation college four year degree / CMEL program teaches more about aviation then a one year AF or Navy pilot training program. A similar civilian one year program could be established. Unfortunately the 90 day wonder programs prevail right now.
