It's not a new thing that parents are expected to contribute, and has nothing to do with fees or student loans: as titchy pointed out, under the grant system, parents were still expected to contribute - not every university student was eligible for a grant, as it was worked out on (wait for it, wait for it, wait for it) parental income for all under 25s.
You might not think it's fair - but it has been that way for at least 50 years.
One of the things that has changed is very many students' expectations: they "can't possibly" share a bathroom with other people, so choose one of those new, independent, student living places, with ensuite and Sky included (in my city, it is cheaper by about half to share a house in the traditional student area ten minutes from the city centre by bus: few do any more); they buy new clothes frequently (and not only from Primark); they wouldn't be caught dead coming to lectures without being glammed up (including fake eyelashes and tan, and from their conversations, seem to buy their make up from various concessions at department stores); they have smart 'phones with contracts; they expect to be able to have takeaways several nights a week; they go out to wine bars and non-student nights, three or four hours a week; they run a car.
Obviously, not every student is like this - but more and more of them expect a standard of living commensurate with a salary of being in employment a good few years. That's fine - they are adults, and can make the choice of fitting a full-time job around a full-time degree after all. But to suggest it's a sudden and new outrage that parental income is taken into account is ridiculous, and to suggest that there aren't ways that students can economise (although, of course, in expensive cities, this is harder: the upside is that there are also more jobs available in eg London) is also ridiculous. There are people with no parental contribution up and down the country who manage, despite not being eligible for any extras - and generally, they become incredibly good time managers: the squeezed middle is the hardest hit, of course, and it was ever thus - but they can choose, as I did as a student, and as many other students do today, to cut their cloth accordingly and do the best they can.
