The south doesn't have it any easier than the north. My town has areas of extreme poverty amongst extreme wealth. I think here there is a stark difference between the haves and the have nots
Ie Secondary schools. Parents who can pay for tutors for the 11+. The kids who don't pass 11+ those parents often fund private secondary on top of those paying privately already. That leaves the state schools with the rest of the kids and high levels of deprivation and SEND.
Kids with SEND, again locally, the parents who can afford it can afford all the therapy our NHS just don't provide, plus pay for reports for properly written EHCPS, pay for legal representation to challenge LAs. The contrast between those kids and those with parents who can't is stark.
I think areas like here the stark contrasts within them is notable.
