@XingMing we don't often agree
so I appreciate your thoughts thank you.
because intelligence is largely an inherited element, regardless of what teachers say
I totally agree! And I speak as someone blessed with that type of intelligence myself (well to a point!) but I'm certainly aware of friends and family who have been done a great disservice by how the education system works in this country and has since the 80's!
People who are extremely talented artists, musicians, tradespeople, mechanics, hairdressers, carers, support workers etc who's aptitudes and abilities are not valued. Yet who contribute just as much to our society as teachers, drs, lawyers etc (I would argue of more use than sodding investment bankers in most cases!)
There are of course other factors affecting ability to make the most of our education system. My own dd left school early due to the schools appalling lack of support around the fact she has a disability which unfortunately during her first exam year landed her in hospital a few times totally unpredictably and unavoidably. Instead of helping a child who was previously on course for high marks and who teachers had confidently said would likely have her pick of unis to catch up on what she missed and support her in her return to school after weeks off not through any fault of her own they treated her like a truant! To my shame I was even sceptical myself how bad it was until one teacher spectacularly lost the temper with me in quite a shocking and unprofessional way! With hindsight I should have kicked up a Merry stink but dd wasn't up for it and I was in bad health myself at the time (which the school also knew). She has now after several years out of education returned to it and is doing very well so far.
But many would have been completely put off by what she went through and not even considered a return to education.
We see that on these boards all the time too, people who were badly treated at school even by the school and it's totally put them off education.
So I slightly disagree on "rule themselves out of the game early by age 14, playing truant and ignoring the potential gain of education" I know and have spoken with many who gave that appearance of "not caring" when in fact what was happening was lack of support - either within the education system (I have one friend who is dyslexic not dx until their 20's who "failed" at school, their partner having a sibling with dyslexia noticed certain things and encouraged them to pursue a potential dx. She has since qualified as a bio-chemist and is now helping develop medicines for a major pharmaceutical company) or within home life. Very very few kids truant purely out of mischievousness.
But ultimately, the attitude your parents teach you is more important than anything else
again that can be a tricky issue.
My parents are very pro education despite having had to leave at age 14 themselves being from very poor working class backgrounds and both being the eldest child, their families needed them to be earning as soon as possible and even a-levels let alone a degree seemed something "for others not meant for us" but they were raised by parents who also valued education and were very widely read and informed themselves as best they could from the sources available to them.
On the other hand both my fathers childhood and then by repeating of history my and my siblings too were also informed by abuse, control and addiction. And people's response to this varies even within the same family differs.
I wanted out ASAP and so left school at 16 with few GCSEs not because I was incapable but because it was impossible to get peace to study at home and because I was barely sleeping or eating due to the stress. I found a job that enabled me to leave home at 17 and then went to night classes to get my a-levels.
My brother and sister chose different paths but certainly influenced by what we experienced at home.
