These generalised north/south opinions are so frustrating.
DH is from W Yorks, we lived there for a few years, now live in Hampshire but are frequently up and down.
Yes, there are areas of deprivation up there, for example areas ruined in the Thatcher era which have never really recovered.
Yes there is money here, but the wealth is concentrated in a small percentage of the population. There are some very rich people in Winchester for example - but the gap between rich and poor is stark.
There are also huge areas of deprivation in towns and cities such as Southampton/Portsmouth/Gosport to name a few. Town centres full of empty shops if you take a walk through Basingstoke or Fareham.
Even in London - try telling people in Tower Hamlets that ‘all the money is here’.
You could argue that public sector workers are in a much stronger position up north. Same wage, cheaper housing/petrol/pretty much everything.
There are also really affluent places in the north.
Any analysis will show you that the greatest concentration of wealth is in the south east, but believe me, the people who have it aren’t sharing.
People are on their arses here too.
