Locals sell to 'emmets' then complain that 'emmets' own all the houses. I don't understand.
Solution: Locals, don't sell to 'emmets'. Problem solved.
Correct you don't understand do you....
Like many areas of the country, the locals never owned the property in the first place.
The London-centric aristocratic families owned the land, up until comparitively recently (I would say the Anglophile aristos, but possibly only the Welsh and Scots would follow...).
Some lands and properties were sold off from the country estates as they fell on harder times between WW1 and WW2, but a lot of this would have gone to smaller landowning farmers, and some tenant farmers.
After WW2 the big estates were forced to sell many more of their properties (and don't forget, these guys owned almost everything in most villages...... all the houses, vacant plots, fields, chuch, pub, village hall)
They soon cottoned on to the fact that there was better pickings to be had by getting their estate agents (see where the term comes from...?) to advertise in London and the other centres of wealth.
Fine from a free market capitalism perspective. Not so fine if you are from a rural village (Cornwall or elsewhere) about to see a surge in property sales to wealthy incoming buyers.
From the late 60s onwards, this pattern has been repeated in large parts of the rural UK, but is obviously far worse where
a) There is a ready pool of willing incomers and
b) Local wages are too low to compete for property
