If students are customers, why don’t they do their research?

A discussion I have each semester with new students is whether they consider themselves to be customers or not. The distinction I’m trying to get them to grapple with is that as students, they are themselves a key determinant of how good the “product” ends up being. In other words, they cannot just place their orders and all expect to get the same result in terms of knowledge acquired. While there are certainly some aspects of the relationship between educators and students that are analogous to suppliers and customers, it’s an incredibly poor model to base one’s academic interactions on, as it encourages passivity on the part of the student, as well as a mindset which focuses on the student’s rights, rather than their responsibilities.
