I don't find it inconsistent. Not-good is not negative, it's neutral. Martial arts skill is good, lack of martial arts skills is neutral.

Also, knowledge is good, education is only good to the extent that it brings you knowledge, and neither mean that you don't drive a garbage truck.

If it helps, replace ditch-diggers with skiploader drivers. Replace assembly line workers with robot repairmen. The point is that somebody will have to be doing something, rather than just directing and allocating people who are doing something.
