Yes it was free if you could get into a university. In the time you reference only the very highest percentage of students met the entry requirements for the old universities.
Then along came Blair, who decreed that every man and his dog should go university.
Every college in the UK suddenly achieved university status overnight, together with a whole new lot of degrees that were useless to get a job.
With regard to your comments re the older generation cornering the housing market, absolute bullshit.
Yes we bought a house, but it's not the fault of older people that the housing market in the UK is disfuncional. Blame successive government's for not building enough houses, blame the bailed out bank's for not lending, blame the big builders for sitting on massive land banks but don't blame my generation for something that is beyond our control.
I have two kids in the same boat as all the others kids in this country.
