I'm also part of the outgoing 3k cohort, and have worked for the university during my time as a student.
My perspective is that I am a consumer in some ways. I chose a "product" I felt was right for me and do have certain basic expectations - e.g. lecturers show up for lectures and mark work within a reasonable time frame, I have reasonable access to the library and other facilities where needed, I have a chance to give feedback, I can discuss issues and problems with a member of staff, I can use support services when needed.
However, I don't think being a consumer means I am entitled to a degree grade I haven't earned, especially if I don't put any work in. I am paying to learn skills, I guess, but not necessarily to pass the course. I also accept that lecturers have a lot of other duties, and won't always be free to see me, and that the university will decide how much contact time is needed to deliver the degree.
I can see how paying £9k a year for 12 hours a week contact time for two semesters doesn't always feel like it is worth it. I can see how, in this situation, students feel entitled to a level of "service".
However, I also believe lecturers and other university staff are stuck between a rock and a hard place- they are getting no more money, but expected to provide a better level of service. They still have the same level of commitments and in most cases there is no money to pay for further teaching staff. Some students are very entitled and make spurious complaints. However, some universities are complacent, and I have seen issues on hear and heard about them IRL where I feel the student does deserve better (dissertation supervisors not really supervising are a common problem). If higher fees mean students feel more able to complain when they are not being treated fairly, then that is a good thing. However, some students do have unrealistic expectations.
