I live in a middle class area. You can tell the parents who grew up working class. They aren't as strict on discipline and the kids don't read as much. Thats probably as far as it goes.
There were no toddlers reading or writing. It just doesn't happen. Not in my son's peer group and having helped in reception with another year group, there was no toddlers who could read and write. There were plenty of four year olds who weren't toilet trained though.
What's been interesting to see has been attitudes to home work. There's been a lot of very vocal hostility to home work with a lot of parents saying they just don't have time to facilitate this. It's notable. The kids who end up at after-school club are much more likely to be in this camp but it's not a hard and fast rule. There are parents who do it without fail but they aren't vocal about it and that says a lot too. They may work full time but seem to rely more on family for child care. I was surprised at this. I thought because it was a middle class area, parents would be all over homework and being much more pushy for it but this hasn't been the case. I think it shows up parents struggling to keep up with it on top of work.
DS class across the board are struggling and I know of quite a few kids who are getting tutors just to keep up. It's not to pass the 11+. It's because they are not getting help from parents and quite frankly school is failing them.
I don't know for sure but I think reading levels are significantly down on what they were five years ago. I used to do reading with yr5 when DS was in reception and his peers are no where near now, plus I know several of the local high schools have started to do remedial English lessons in yr7 and 8 because standards have slipped so much. This INCLUDES one 11+ grammar school with an exceptional reputation doing phonics lessons! (My friend and I suspect this is because the large number of Hong Kong kids who have moved to the area have been coached within an inch of their life to pass the entrance examine but can't actually speak or read English beyond that). It's insane. It must be affecting the other kids who passed the entrance exam. The parents who thought they were escaping that must be sorely disappointed. In some ways it's reassuring the schools have identified the issue but it's also concerning. The SATs results of this years Yr6 group will be enlightening. They were in reception when COVID happened and I've heard for years how problematic they've been - not just my son's school or other local schools but for friends with kids who live elsewhere in the country. It marks something of a change in attitude in parenting too - these are the first of Gen Alpha really hitting high school. Gen Alpha strictly starts with 2012 babies so it's crept in the last couple of years but I think next year will be more pronounced.
There is a vocal group of no phone parents but ironically they are also the parents who allow their children free access to YouTube and let them game a huge amount without properly understanding either. It blows my mind - it's all virtue signalling. Again the parents who are actually strict with technology don't make a song and dance about it - but they don't necessarily ban phones / tech - they manage them instead. There's a subtle but important difference. One option abdicates responsibility whilst the other understands there is an issue and actively parents it. Then there's those who just don't care and let their kids on most things because 'their friends are all on it anyway'. So I think there's really three phone/tech camps not two. The divide is interesting - its not on class lines particularly, it's on social circles. The parents of the 'Cool Kids' are the vocal phone banners and don't do homework. The nerdy kids tend to be in the managed usage group who also do homework.
What happens in this area is likely to be replicated in other middle class areas and will filter down. I do believe there's a growing problem in parental involvement generally. That's going to impact on a lot of middle class kids in a way it hasn't in the past. Tutors don't give emotional support, manage behaviour and they don't manage tech.
So yes I think there's a class divide but I also think there's a support network divide in the middle class. Many middle class parents are struggling in areas they haven't in the past imho. I also think there's a split between early adopter parents and parents who don't do tech. DH and I are early adopters and don't think banning tech works. We heavily used the internet in our late teens and early twenties. Our peers who didn't do broadly have much more of a ban attitude to tech. So DHs techy friends and aquantainces are behaving differently to others regardless of class. Id argue that ideas of working and middle class are probably too simplistic and inadequate and we possibly have an emerging tech class to a degree.
It's a complex picture which I'm sure someone will study and write endless reports no one reads and no one acts on. I think there's a change occurring for sure but I don't just think it's about this economic gap, I also think it's about other emerging gaps in social support and technological understanding.
