'Mass exodus'

[NorthernRaider]

The poorest people in the UK are the rural poor who have to spend more on transport to access public services, they usually or often have only a very limited bus service, no libraries, no cheap supermarkets, no cheap petrol stations, few liesure facilities, they have to travel much further to access medical care etc. Many people of limited means elect to live rurally with poorer public services because they prefer the slower pace of life, they sacrifice the access to other infrastructure and services in order to be able to live in a village.
Of course there are also those who have lived and worked in villages there entire lives and are of limited means. Traditionally the most impoverished people in the UK when it comes to income, access to services etc are those in places like the West County, Welsh Hill farmers, and agricultural workers in the dales.

Moving out of London IS feasable for most Londoners its often ( but not always) lack of will, I have pointed out before that you can buy houses in rural villages up here from £45,000, you can rent from £300 a month, and these villages have good bus access to Durham, Darlington, Teesside, and Wearside so commuting is feasable for work.
