Universities have no incentive to steer students away from their areas of interest, but if it's this hard for a humanities major to earn a living wage, we're producing too many of them. Humanities departments have a vested interest in maintaining their output but I can't help but think that they're hurting themselves in the long run.
Humanities are an important part of a well-rounded student, and there are lots of instances where a humanities minor with a technical or business related major is a powerful combination. I'd hate to see the humanities die, but can they keep living like this? There should be more outrage among their graduates ... when that happens (and I've seen a few articles), things will get much harder for them.
As an aside, making 0xx and 1xx level introductory classes in the humanities, which are required as part of the GenEds or BDRs (Basic Degree Requirements) too hard is in many cases teaching students in other disciplines to hate you ... you should draw those students into your minors programs.
