The problem is not with the rich or the poor, but the squeezed middle.
The problem is not particularly with London, but with provincial universities.
My DS1 is in London, and he gets a bigger loan (£5000), and has a wide choice of accomodation. He doesn't have day-to-day transport costs, and the supermarket costs are the same as anywhere.
DS2 is in Bristol. His loan is ?£3500. He has no choice over halls, which cost £4200.
DS1 has shared room, no bathroom; DS2 has single ensuite. DS2 didn't have a choice of cheaper accomodation, so has to pay the higher rate.
We are paying DS2's hall costs, and he will use his loan to pay for everything else. Not sure how the figure of £9000 is worked out.
Having had both DSs home for the summer, and both of them gone now, I do realise that they eat a lot while they are here, so that is a savings for us.
Both boys were in private school at around £17000 pa. We are saving quite a bit now.
I am of the camp that believes they should be responsible for their own higher education, so should take maximum loans. I do believe that students have needed loans for many years now, so there should be no surprise to parents.
I was at university in the mid-80s when the grant system started to shift. When I started my degree, the grant ranged from £410 - c£1500. Midway, it shifted to £205 minimum and I think it went to zero shortly thereafter. Clearly, parents needed to make a contribution. You have to be a very naive parent to be taken by surprise by this nowadays.
The fees situation is relatively new, but this is all covered by loans, so no one should be put off doing a lucrative course.
