It's not just tutors.
The family who bought in the catchment of the better school down the road and paid a premium because of course, like everyone does, they cared about their children have probably done many if not all of the following:
- paid for their children to have swimming lessons
- paid for their children to learn a musical instrument
- taken their children on holiday either abroad or to a place different from where they are growing up
- paid money, whether in fares or admissions, to go to a museum
- paid money to go to an art gallery
- paid for their children to do a sport outside school
- paid for their children to do a creative activity outside school
- paid for their children to do an academic activity outside school (Kumon, coding camp, French club, whatever)
- paid for their children to do an activity at school of any kind
- bought their children books just for fun
- taken their children to a historic house or other interesting place which cost some money
- taken their children to the cinema or the theatre
There are probably a billion other examples. I personally know lots of families who would never be able to afford to do any of these things and obviously their children are disadvantaged as a consequence, compared to children who are able to do these enriching activities. Would be interested to know how many of the 'we go state because it's the moral thing to do' have never done any of these!
I know families who can't afford the cost of a £3 movie night at school, never mind thinking of the theatre or a museum or a coding camp.
I know a child who lives less than ten miles from the Natural History Museum - we went there on a school trip and he was blown away. I told him it was free and he could maybe ask his parents if they could bring him back one day and he looked astonished. I bet they didn't (he probably didn't ask).
I know another child who saw the ceiling in the chapel at Windsor Castle on another school trip and was clearly just completely enraptured. But his parents will never take him to see even Hampton Court which is much closer than Windsor.
I know another child who I saw in the supermarket aged 10 trying to buy a basket of food and her mum's card wouldn't work (because there was clearly not enough money on it) and she was completely stressed out so I paid for her basket of food and told her not to tell her mum (because I didn't want the mum to think she had to pay me back).
No matter if you send your children to state or private schools, their own family circumstances will make a bigger difference to them than any school.
I would like to see more money aimed at giving children opportunities to do the sorts of things I listed above and more money aimed at low income families so they don't just have to stress about if they have enough to pay the bills or feed themselves and can perhaps offer their children something above just existing. Schools are the least of it in some ways.
