I didn't agree with Jeremy Corbyn on much, but he was right when he said that high speed rail links from London to the North would probably only encourage that process. The pandemic might have brought people into the provinces who might otherwise have had to live a lot closer than that, but without commensurate investment in local infrastructure for people whose jobs don't allow the same mobility, it just ends up in gentrification rather than any actual support for those communities as their own entities. It's like the way people buying second homes in the countryside have hollowed out the affordable housing market in those places rather than breathed new life into the actual places.
As someone who only lately got to work from home at all and felt ignored by the media discussion on work from home, I'm very mindful of the privilege and try to act accordingly. Otherwise yes, we will end up in that situation, and it will be a big problem for sustainable community life. However, I think there's a return to the office under way because complete atomisation was also unsustainable for businesses in the long run; when I left my reception job in November 2023, people with corporate lanyards were starting to fill up trains again. While you won't ever put the WFH genie back in the bottle again, I think a lot of people are starting to find moving away from London wasn't the best idea in the long run.
@Magdalia -- good to hear that Cambridge is growing that way. I spent some of my teenage years in Bedford and, while I was anxious to get away from home into the big city, three years of university in London was enough -- I came back to where my semi-nomadic parents (ok, they make the Bedouins look settled, but my dad was a civil engineer and you just have to go where the work is) had moved to in the Reading area and moved to Basingstoke when I got married. (Ironically once I was an adult and could have plausibly not gone with them when they had to move again, they also reached the point in their careers where they had more choice as to where they lived.) Even after being widowed (I had the great misfortune to marry someone with a genetic time bomb in his kidneys; I'm 45 tomorrow as it happens and it's already been more than 5 years since he passed away, missing the pandemic by about seven months), I stayed here because it has the perfect balance of green space and urban amenities. I work in provincial NHS property management, and when I've been to our London HQ, it reminds me just why I wasn't sorry to leave twenty years ago. Too crowded, too chaotic, just too much.
Some of my best memories have been on train journeys and I spent 10 years commuting between Basingstoke and Reading. It would be a real shame if London continued to suck everything into its orbit, but what you've said gives me a lot of hope.
