To paraphrase some of the inflammatory comments I have just deleted (you do attract them don't you?)
"You friend is somewhat narrow minded and has a warped perception of life."
It is a parent's duty to enable their children to reach their full potential, but they can't really do anything about the innate intelligence of their offspring.
As for your comment about non-grammar schools being a shambles, well, yet another sweeping generalisation (You are good at those
).
There are some extremely good comprehensive schools about (many run on grammar school lines) and while selective education had its merits, one of the downfalls was that insufficient resources were spent on the secondary modern schools that were part of the secondary school system.
Sadly in the interests of 'equality' the decision was taken to try to abolish the grammar schools, rather than put more resources in to the secondary modern.
And yes, I did pass.
