Only because that's what college has become. I loved studying my field for four years, free of most of the vicissitudes of life that would otherwise prevent me from being able to focus on an education. I guarantee you a lot of people would like to get a degree simply for the sake of learning, and to become a better person. Hell, I'd take a few classes if it didn't cost like $800 per credit hour. This whole "college as job training" thing is a self-fulfilling prophecy, and none of the innocent people subjected to it are particularly happy with the situation. They are not, crucially, in a position to change that.
