Yeah exactly.
@TheCountessofFitzdotterel that's what I was trying to put across, and the article that @Xenia shared somewhat echoes what I was trying to say. Although I'm in the NW, not the NE.
Of course there are areas like Trafford, with a lot of grammar schools, and the culture + house prices to follow. A lot of recent HK migrants have chosen to settle there for this reason. But I found the general culture here in the NW very different from London, again at the risk of generalising.
Entirely anecdotal evidence....
I'm from a South East Asian country . Went to a prestigious London university. I got a scholarship - wasn't from a privileged background. My A-level college made me apply to UK unis as I had stellar grades but I researched, wrote my PS , found scholarship info in the course of googling PS's and did everything myself. This was close to a decade ago. There was entirely zero question of not taking such a golden opportunity, 'support network', whatever. I got my first passport, on the plane and off I went alone at 18.
DH is from the NW and baffled by all this although half his family are Oxbridge high achievers (and the other half are the exact opposite, which he took after. He's great professionally but bad at exams). When I moved to the NW I met lots of people who just didn't see the point. Bright people who could have applied, who otherwise went to unis like Manchester, even Edinburgh, hardly 'low achievers' it just didn't appeal to them.
My university name does open doors for me, but after all my time in the corporate world people at the top come from all sorts of backgrounds. I
DC will be fully supported on whatever path, I guess they might follow DH more as, unlike me, they didn't have to make their own way in the world. But, while I'd tell them to grab an Oxbridge offer with both hands DH sees it as just one of many choices.
It's very complicated and nuanced...
