Unfortunately a lot of this is because many faculty of 'liberal arts' colleges/universities believe "we are here to give an education and open student's minds and broaden their horizons" but even more often I have heard "liberal arts are not intended to be job training institutions"

so it is a much easier sell a creative writing major in a faculty senate or something similar than Aircraft Maintenance. And when you do get Aircraft Maintenance it usually gets tucked into the engineering or business schools in order to survive.
