I'd say it has more to do with the person than the curriculum. Clearly technical or science based fields will fare FAR better than lib arts, but it still relies on a persons ability to apply that knowledge in a wide variety of situations.

IE. How many of you know engineers that can barely tie their shoes? or teachers that could fix many cars, repair many homes, have a basic knowledge of orienteering, etc...

Sure. Medical, farming, etc is important, but so is the ability to find a way to generate electricity and purify water. Not to mention mostly lost arts like working wood or stone by hand, or blacksmithing.

We live in a remarkably interconnected society, and there are precious few people that could do it even in small groups.
