Stressed- since you addressed me directly, I will reply.
For the record, I haven't even mentioned private schools. I'm not entirely sure they are particularly relevant to this debate- except that, because of them, and of grammar schools, most of the people who have most to say about the education of the majority of children have no experience of the sort of schools most children go to. Or if they have, it is at least 20/30 years old. Which is as good as not having any experience.
And as for being "the only person who has not laid out clearly what I would do to improve the situation"- really? I haven't seen workable plans on this thread , just a lot of "Something Must Be Done" rhetoric.
We can't even agree on what the problem is. Comparing the UK to the Asian model is useless- apart from anything else, there are loads of no/low skill jobs in for, example, manufacturing and agriculture in those countries so there are actually jobs available for people with little or no formal education. That is no longer the case in this country. And I would be interested in knowing how many children don't go to school at all- what happens to them? The publicity pictures of eager children on their way to school in African villages are just that- publicity pictures. Fantastic for those children, and they mean a school full of eager, motivated, driven children who want to succeed. But a 10 mile walk is extreme "back door selection"!
What do I think should happen in this country? I don't know. What I do know is that for most of the 40% of low achievers in my ds's school, 5 GCSEs at A*-C is completely out of reach. And asking them to get that is setting them up to fail. What they do now is a mixture of GCSEs and BTecs- very few leave school with nothing. I predict that more will leave school with nothing under Gove's new regime. I will be delighted if I am proved wrong.
It's also important to remember that having a significant number of people who find academic work difficult is not new. What is new is an employment market with no place for them. The sort of jobs they used to do are now being done by a similar demographic in the Far East.
