To me, it doesn't make much sense to live my life as a fallback plan. I'm not going to spend 100K on an education that I would only want to employ in a worst-case scenario; rather, I want me education to prepare me for my future. Period. Computer science? Yes, it's nice, but it isn't what interests me, and I most certainly wouldn't want to spend four years studying it. Physics? Most certainly applicable, but not what I'd want to spend four years studying. Aviation? I was bitten bad by the bug, and I would personally love to study it for 4 years. To repeat it one more time, what makes an aviation degree so much more useless outside the field of aviation than any other degree?
