Sid, I fear that we are about to disagree again.
'more likelihood that our kids can stay and bring up their families in Dover'
I was raised in the West Country in a town not dissimilar to Dover in terms of population as one of four siblings.
All of us, benefiting from both Grammar School and University education have 'done well', all having been able to retire to a very comfortable lifestyle long before 'normal' retirement age.
I visited a school re-union a year ago and was somewhat saddened by the parochialism and general naivety of many of my peers from school who had never left the district.
They had all done well. Solicitors, estate agents, teachers, stalwarts of the local community they were leading lights in the community being magistrates, local councillors, rotarians and masons. I had a really boring evening.
I am glad that my non of my four children have chosen to remain in the district where they have been brought up, and would actually have been rather saddened had they had such limited aspirations that they had chosen so to do.
