A lot of people my age, encouraged by the '50% of school leavers should go to university' policies of previous governments are the first in their families to go to university, get degrees and graduate jobs.
Of course they are going to be unhappy about it and to dismiss that as 'middle class' anger is trite.
After all, these parents are the very people who, when they were 20, would have qualified as 'working class' under this scheme. They have a right to feel betrayed.
