As others have said on here, the 9k fees don't only pay for teaching, they pay for the library and information services (which are pretty expensive), lighting / heating etc of buildings, subsidised sports and coaching in many unis, the guild of students and student societies, the chaplaincy, the counselling and careers services, etc, etc ,etc.... all things which contribute to students' experience of university.
Students generally complain about the few contact hours at university, often thinking that more hours spent with staff equals a better course. Part of the university experience is about self learning - the lecturers tell you what to read, and give you the skills you need to get a good degree, and, of course, some of the knowledge you need for that, but the rest is up to you. Every lecturer with a PhD is an expert in their particular field; the tuition fees give you access to these experts who tell you what 'standard' (in terms of a degree) your work is. Just cos you pay fees, it will not automatically entitle you to a 2:1.
. As for libraries, it's usually the subjects that are treated well that appreciate these facilities and those that are treated badly that complain.
