I've seen yet another thread where the OP is lambasted for being in a SE bubble (she was in a bubble tbf, but a bubble of incredible dimness), and many posters talk about The North as a place of scant opportunities, cheap housing, low wages and general divorce from The South, which is generally considered as the land of milk, honey, opportunity and high house prices.
It's very divorced from my experience of both places. I'm from an area in The North that is one of the wealthiest political wards in Europe, I went to work in the city after University (25 years ago) and despite having a very middle-class upbringing and accent, my flat vowels were treated as something of a curiosity (and they're really not that flat, everyone up here considers them 'southern') and Sheffield, my home city was, and still is, perceived as being some 'flat cap and whippets' place, despite having one of the highest proportions of professionals per capita in the UK.
My take from that experience was that born and brought-up Londoners are the most parochial people that I'd ever met. I had a much more 'worldly' experience being brought up in thr middle-class North than that of the supposedly urbane Southerners.
But still it goes on, people speak of The North as some kind of otherworldly shit-hole where the denizens scrabble around for cheap terraces on MW jobs and anything worth happening happens in The South.
Leeds, Manchester, Sheffield, Newcastle, Durham, York, the smaller towns and places where there's a huge amount of creativity, wealth creation, and professional people living fine and prosperous lives, and have for generations.
I just cannot understand the stereotypes that divide us so badly.
And yes, I also know and understand industrialisation and post-industrialisation that has affected certain areas of the UK. I'd say the area of the UK that's been hit worst by post-industrialism is the Midlands though. But no-one talks about that, or the poverty in the SW, it's always THE NORTH.
