So many people have absolutely no awareness of just how critical it is to have a healthy independent school sector for everybody in the country. It serves two key functions:
- Independent schools are not dependent on government funding. They are free to set their own standards with regards to the quality and quantity of education they provide. This raises the bar for everyone by putting pressure on government to keep state funded education standards high. They don't always reach the same levels, and opinion will be split on whether a state education is as good as an independent one. But there's no doubt schools are underfunded as it is, and without an independent sector, that does a completely different cost/benefit calculation, those standards would gradually fall away even further.
- Independent schools are free to teach a curriculum that they deem appropriate, and by extension that the families of their students deem appropriate. The government of the future may one day decide it's not important to teach children about, e.g. WW2 and the Holocaust, or the theory of evolution. Free from government control of the curriculum the Independent sector helps ensure people are educated on what people other than politicians feel is important.
There is a third which involves the freedom to combine religious and academic education, but most people have a hard enough time buying the fact that 1 & 2 are already a sufficiently critical benefit to the whole of our society. When you hear talk of of "banning" private schools, just think "handing complete control of education to the next extreme left/right wing government this country elects in 10, 20, 50 years, and it's the stuff of dystopian nightmares.
Independent schools with charitable status are by definition not businesses. They don't have shareholders earning profits. Removing that charitable status would have undesirable consequences, not least of which is making it unaffordable for even more families, leaving them only more elitist institutions.
It is a terrible policy loved especially by the hardline authoritarian left, but one the authoritarian right also feel ambivalent about at best.
If you are a libertarian, if you believe in freedom, you should strongly oppose attacks on independent education. Unfortunately many people can't see past the unavoidable unfairness and elitism that comes with it. Many don't even care that the alternatives wouldn't be better for them (the politics of envy), but worse still most are too naïve to imagine that the alternatives would be worse for them.
Attempts to sell the benefits of abolishing independent education as "more money into the state sector" and the frankly laughable "more sharp elbowed parents demanding better" are just fantasies.
