Remember, economics assumes rational actors. We have loads of students in school because they think they have to be, but don't treat it as an investment. For most fields, tuition is already way above equilibrium, because schools and students alike believe that demand is inelastic: either you get a degree, or you're a second-class laborer. By not having this information, they can't be rational, and continue to "buy degrees" even though MC > MB.
