If there were truly inclusive comprehensive education, students would not have to travel great distances to school because of barriers to their attainment or lack of them.
So. just to clarify, you want to go back to where there was no choice and you automatically went to your nearest school?
You want to scrap all selection, i.e. no faith schools, no grammars, no schools with specialisms (such as for sports, Maths, languages, science, etc.).
You basically want every comp to be identical in terms of the subjects, extra curricula activities, pastoral care, etc., that they offer?
After all, there can be no other way to offer every child the same opportunity, other than to have a massive network of comps all doing the same thing.
That sounds like a massive U turn after years of the mantra being "choice" where you had the freedom to send your child to a school specialising in Maths if they were gifted in Maths or sports if they were a talented sports-person.
Is that really what you mean?
