tuition fees

we are told that too many people now go to university.so it appears the answer south of the border is to raise tuition fees.we are also told that graduates will not have to pay until they are earning £21,000 or more.yes seems straight forward enough.but universities are short of cash now so if i had the money and wanted my child to attend a top university i could offer the money up front,no?as for too many now going into higher education how do we chose who should not go.well if i had just spent x amount a term sending my child to a private school and be told no room at university.......do i see something here. surely not.
