NJ - you, like me, are part of an education system that no longer exists - and that is a good thing in my view.
You were seriously fortunate that your parents valued your education, and you had a decent start in terms of values learned at home.
Sadly, a couple of generations has seen that attitude all be eradicated, and that is not helped by government approaches to education.
Simply put - education is a political hot potato because every voter has an opinion about it, because every voter has been to school, and therefore thinks they know something about it.
Governments respond by vote-catching, punting concepts like 'parent power/' and similar guff, and appealing to the voters they think they can catch by telling them what they want to hear.
This goes hand in hand with an utter inability to leave any education policy alone long enough to bed in, before being changed and switched around, hence the terminal morale of teachers.
The Conservatives preach grammar shcoools, not because they are effective, or suitable for a modern society, but because Tory voters can wax noastalgic about good it was in 'their day', and fondly imagine that this will bring back those days in which you grew up.
Those days are gone, because that society is gone, and it's not coming back.
You might as well wax lyrical about the England football team in 1966 - it's not like that anymore, but pretending we can bring those days back keeps fans watching.
Pretending grammar schools are a good thing will keep Tories voting, and let's not pretend that this is what the debate is about at the end of the day. To pretend anything else is to ignore the obvious.
