Ah, choice.
Up until 150 years ago you had several options in relation to educating your children: Sunday school, working class fee-paying dame school, middle class fee-paying dame school, tutor or governess, charitable grammar school, public (i.e. private boarding) school. Quality was variable but at least you had choice, albeit rather skewed by social class.
150 years ago the Church of England effectively did a bit of a land grab in relation to education, and developed a more or less monopoly position in relation to elementary schools (up to 12 or later 14). About seventy years later, the Government reinforced the C of E's position by successfully outlawing working class private schools in a particularly underhand way (details on request), leaving middle class and upper class private schools untouched. That was the beginning of the end as far as choice in schooling for working class children was concerned.
Whizz forward to 1944, and we see the Government making secondary education free, and most local authorities introducing the tripartite system of grammar schools, technical schools and secondary modern schools. This worked for some children and not others, as we know. A key factor in the apparent failure of technical and secondary modern schools is that they were underfunded in comparison to grammar schools, and the 11+ examination results were not necessrily a true reflection of children's abilities.
In the light of all this, the only way I can see of making schooling fair and equal is to make it illegal for families and local authorities to spend more than a certain amount on their children's education, so there isn't such a great disparity. However no Government in their right mind would ever suggest such a thing.
In the meantime there's an element of moving deckchairs on the Titanic, tbh. People in towns get choice, people in the country don't. People with girls get more choice than people with boys. Christians get more choice than anyone else. And you can only 'choose' from a government model for education that many regard as woefully defective.
We are frittering away the greatest asset this country has, namely the intellectual capability of its population.
