Getting a degree in something other than aviation is not as useful as you'd think. It sounds like a great idea in theory, but in reality, a pilot will spend years flying for an airline before trying to move onto another career. At this point, all employers care about is real world experience. Look at it the other way. Let's say you get an aviation degree, then become a police officer for 10 years. After 10 years, you decided to get back into flying. No one will offer you a job flying due to recency. Other fields are the same way.
