When the 1944 Education Act was put into force shortly after the end of WW2 by the Attlee Labour government, they were able to push a lot of extremely radical things through because they had a huge majority and most British people agreed there was a need for change. The Welfare State had arrived, the NHS had huge support and in education the school leaving age went up to 15 (from 14) and children were now entitled to free secondary education instead of spending their entire compulsory school years in the local elementary school, which took 5-14 years old and taught mostly just the 3 Rs. There were to be grammar schools for the brightest, most academic children, to be selected by the 11+ test. Then there would technical schools for children considerd to have an aptitude for that sort of education. The majority of children would go to Secondary Modern schools which would teach a broad-based curriculum with plenty of opportunity to learn practical skills alongside the more academic subjects.
It didn't work out quite like that, of course. The technical schools largely failed to materialise and entry to grammar schools was dominated by the middle classes. However, there were enough bright working class children getting a decent education that social mobility increased enormously. An additional effect was that far fewer parents paid for private education. They were already paying much higher income tax and the grammar schools were doing a good job, so why pay for a private school?
This is what Labour ought to be concentrating on now. Put up income tax so everybody pays towards getting the NHS and state education back on track. If state schools had good buildings and facilities, a full complement of appropriately qualified staff, good behaviour and discipline, excellent pastoral care and support for children with all kinds of difficulties, a broad-based but rigorous curriculum and all the other things that private schools offer, why would anybody pay, except out of snobbishness?
It would be an investment in the future for our government to do this. We desperately need a better educated workforce with good mental health if we are going to continue to be a prosperous, peaceful country.
What we've had in the last six months, though, is relentless negativity. The tiny amount of money this VAT change might generate is a drop in the ocean of what's needed to sort state schools out and what it's mostly done is give Labour activists a group they can demonise and blame, namely parents who send their children to private schools. Disappointing.
