How much do you think our school system is to blame for much of the anti social behaviour we see from British kids?

We didn't particularly have any set clubs/activities but we had two different centres at least, they were usually manned and opened by locals (retired elderly who've lived in the area forever and was everyone's adopted "auntie" or "nana", local councillors or people who did youth work) but they always had some games thrown out, things for drawing and similar. Usually had some juice and snacks put out for us all so we could run between the park and the centre. It was right behind my house as a kid too which was an added bonus. There wasn't much going on usually but it was somewhere to go, and you got to know everyone in your area too. I left for a good while but came back for family and I can still point out where a good portion of those helpers lived, some still around and living in the same house. I couldn't tell you about anyone else who lives in the area though as everyone now mostly keeps to themselves. I remember as a kid our town would have a large float procession for local businesses and charities. It wasn't anything fancy, said business/charity got thrown a truck a couple days before the event and you had to pick a theme. For my local area, it was our local pub that did it (for context, my mum was manager there so I was always roped in anyway). Whole communities came together to decorate these trucks, all different age groups. You'd spend about half the day driving around the town, dressed up on the truck, or in front of it as part of the band, waving to everyone who came to watch along the way. All the trucks would meet up for a "winners announcement" (1st, 2nd, 3rd and a few extras) and then go along the seafront for their "winners parade/song" (winner would pick a song to be played by all) before going home. I remember a good few varying community charity runs of similar standing too, funny memory of being pushed around in hospital bed by my mum and her friend whilst my friends parents did the same for them (other businesses were in on it too pushing around people in beds) to raise funds for the paediatric unit at the hospital - not so funny is they let me fall off at one point though! Never see anything like these things these days, completely fizzled out. Out of all the places I mentioned, now only one of the centres exists. Pub got torn down and made into a care home, whilst another sits up the street completely derelict, wasting away and has for about 5 years at this point. The other centre is now a block of flats. The remaining centre has a few clubs and things going on, and honestly, kids in OPs mentioned age bracket absolutely ruin it. One of the clubs they have is a small "Gardening Club" anyone is welcome but especially those with extra needs or mental health, it's mostly the former including a girl I grew up neighbours with for the first handful of years of my life. They spent months digging, planting and growing a lovely little area next to the centre to flourish during summer, looked absolutely lovely and a nice colourful addition to all the green (it's next to a large field and bike track) - grew a few fruit and veggies, then some shrubs and flowers. Teenagers jumped the fence and proceeded to just kick it all around, destroy it, dig it up, bring their dogs in to it to do you know what. The centre itself got a lovely paint job (it's just white but had lots of lovely murals done by some of the kids that use it with a local artist that does clubs there during summer), local teens will spray paint over it often. Thankfully it scrubs off without damaging the original mural. And it's really sad honestly, even as a teen that likes to cause a bit of mischief sometimes in the local area (I think probably the worst 'mischief' we got up to was a bit of underage drinking, noise and some knock-a-door), we never considered damaging properties or people's hard work for the sake of mischief or whatever.
