OK everyone who (correctly) says that you need to consider the ROI on a degree before investing in it: be aware that in high school kids are taught DIRECTLY AND UNAMBIGUOUSLY that an art degree is a good and effective thing that WILL get them a job. Be aware that it is only AFTER attaining that degree, and the debt that comes with it, that they try and fail to enter the job market. Foreknowledge WOULD improve or children's lives, you're right! Too bad it runs against causality. No, they DID do their due diligence. They were simply lied to.
Bottom line: most people with art degrees spent their entire education up to college being told that they MUST attend college, but that any degree at all would be equally useful, by teachers and family and our culture in a generalized 'assumed knowledge' sort of way. They think they know exactly what they're doing.
