I'm not really commenting on whether it is good that the state helps fund education, I think in many ways it's positive.
But there has been a change, a few generations ago now, about this. At once time it was up to families to educate kids, either to pay tutors, or to pay fees, or to teach their own children to read and write and do sums. Charitable institutions took up some of the slack with things like Sunday schools and then there were also a lot more fee paying, but affordable, cottage schools. And of course many children left school at 14 or 15 to work (some with better reading, writing, and sums than they graduate with now.)
The basic idea of families however was that they were responsible to see their children educated, and often very local organisations like their churches helped out.
The state eventually became more involved because it was seen as a good way to help kids but also good for the economy to see children well educated.
This has really changed people 's attitudes over the years however, in a way similarly to the state provision of health care. Many parents now do not think about families as having primary responsibility for education, it is the job of the state to provide almost everything, including bussing or taxis if necessary, and todecide what that education should look like. There is suspicion in many cases of parents who want to home educate, and even private education to some degree, at least among many Labour voters - as if they are over-stepping and impinging on the state's right to educate children as they see fit.
This is a really differernt basic attitude and leads to differernt behaviours and expectations. It means is many people feel very entitled to have the public purse pay for all of the needs of their children in terms of education, not only when it is an absolute need because the parents cannot afford it, but where they can. For example, I have known people who could reasonably drive children to school say they should not have to because it is the responsibility of the state - why should they have to be put out, maybe manage their work schedules for example, to drive their kids to the school?
