I think this is one of those things where on a utilitarian/technocratic basis there are strong arguments that some settlements should just be abandoned. I often wonder about some of the former pit villages in County Durham the likes of Horden or Blackhall Colliery (nominative determinism?

). Once the mines shuttered in the late 80s and early 90s what was realistically the point of these settlements anymore? They either didn't exist prior to the mines or were little more than hamlets with a couple of cottages before the mines. Why bother pouring resources into settlements with no purpose? They seem to just now be misery factories to a great degree. We spend vast sums of money on enabling people to live in unremitting poverty for several generations in a row at this point. Wouldn't it be better spent on moving people to places where there is more opportunity?
But, life and humans in general aren't very good at being utilitarian/technocratic. Perhaps its just me but the thought of Horden colliery closing in 1987 and then in 1988 we load the 8,000 odd residents onto buses and ship them around the country to towns and cities feels wrong, feels like something a Fascistic or Stalinist regime would do. The forced displacement of people is something which has a nearly unremittingly dark and grim history. Both here at home but also abroad. Even when done with good intentions it seems to wind up causing tremendous damage. Equally the idea of just saying that you can continue to live in Horden but we're not going to be providing you with any financial support, no benefits, nada unless you move hardly feels equitable either.
Somewhere like Horden can effectively survive in the modern era because we have a welfare state even though the settlements themselves are now exist after their purpose for being created (or expanded) has gone. 100 years ago if Horden colliery had shuttered, the people living in Horden would have depopulated the village themselves because they'd have to find another way of supporting themselves. But is that really a good thing? The sort of poverty we had a 100 years ago makes poverty of today look like a life of luxury. I'm not convinced going back to that is sensible for anyone.
