His experience at Leeds is not uncommon.
I originally graduated from one of the better known universities in 1983, and returned to post-graduate study and teaching in 1989. I experienced an even worse scenario then he - teaching as a part-time temporary lecturer at several of the 3rd tier universities (polytechnics).
Even when students turned in work that was totally incoherent (unfinished sentences and half the size of the minimum word count), I wasn't allowed to fail them. This was on modular degree courses, were most (if not all) of the assessment was of such submitted work.
For years I witnessed half the students turn up to class with no recriminations against the non-attendees, and with only half of the actual attendees having read the 1 or 2 articles which were required reading for that class (photocopies of which they had been given previously, so they didn't have to find the original journals themselves).
The overall level of education and comprehension was appalling. I realised that pursuing such a career was a path to frustration.
In 1997 I decided I couldn't be part of this sham any more. I have friends who had gone through the same experiences as I, and they too decided to quit and find new careers. The story of one of them was even written up in a national newspaper ten years ago.
I have other friends who teach only at post-graduate level. They are shocked by the lack of basic maths, basic grammar and basic essay-writing skills of the graduates they teach. And in their institutions they too provide the students with all the reading matter, so that these post-graduate students don't have to find their way round a library or find out anything for themselves.
Degrees from UK universities were now meaningless, and it was only a matter of time before the wider world found out.
What will probably happen is that employers and/or students will realise that in the majority of work-related degrees the degree itself doesn't indicate anything in terms of skills or competencies.
Several of my neices and nephews have gone to university. Whilst I went there to study, their principal purpose is to party.
My partner is Thai, and I know several of his family and friends who graduated from Thai universities. Some have completed post-graduate qualifications. Yet they would never read a book that was more complex than Harry Potter (even in Thai). Nor would they ever go to a museum or art gallery.
Degrees have just become something that most people do either as a way to move out of home safely and/or a stepping stone to a job. For most graduates there is no sense of education being important in itself.
