No, spoken like someone who knows something of the subject. And you're wrong about where I live as well.
I know, and between you and I this is something that people in my line of work sometimes forget, that data does not drive outcomes. It is the evidence of activity is all. The activity of what you so condescendingly call the majority of the UK population, urban and rural dwellers. The point of data and business analysis is not to change peoples behaviours, but to deliver to businesses insights and understanding of those behaviours in order to better serve them.
The large supermarkets did not rise to dominance by springing into existence in a creationist moment and then tempting in shoppers from the butcher, the baker and the candlestick maker. They rose up and expanded into the space created by a change in shoppers expectations and behaviours. This was driven by a number of factors including, but not limited to, a change in family working patterns, increased shopper mobility, changing tastes and demands, domestic refrigeration and food technology.
Village shops, the ones that have survived, adapted to this by changing their focus from offering a little bit of quite a bit to convenience items with the occasional bit of local produce thrown in. They cannot, so do not, compete with the supermarkets for range or price. I accept that there are exceptions to every rule, near me for example is a farm shop complex that does a roaring trade in meat, veg, dairy and high end dried goods. Ironically, it's principle customer base is urban families with high disposable income. People from the village tend to go elsewhere to the supermarkets.
Simply, supermarkets did not put village shops out of business. Customers, or rather the lack of them, did that. Those that have survived did that through adaptation. The supermarkets themselves are now facing an adapt or die moment driven by, amongst other things, changing working patterns, changing customer concerns and priorities, the rise of internet retail, changing demographics etc
