"maybe is choosing to live in town also a "lifestyle choice""
That's true for some and just 'reality' for others. Over the last 50 years increased mobility has become possible/expected. The M8 made it easier to live in West Lothian. The bypass made it easier to live in East Lothian.
In a previous generation (some) people went home to Morningside or Corstorphine (by train) for lunch!
"No offence meant to anyone feeling pointed at at this point!"
I think everyone has reasons (conscious or otherwise) for their choices/compromises and will, to some extent, justify them. I remember years ago hearing on the radio about a man who took the train every day from Bournemouth to London because he wanted his children to be brought up somewhere nice.
Thought that was a bit extreme.
It's all about expectations/aspirations - and individual choices. I'm glad I wasn't brought up in 5 (or more) people in a single-end days. Reasonable sized flat suits me fine. I'm not sure how far I would be willing to have as a regular commute. I once had to go to Glasgow about twice a week for six months which was a bit much - even though travel time/cost was part of the job!
Edinburgh of course is relatively unusual for a UK city where a lot of people still want to live close to the city centre and, unlike many 'inner cities', it's not cheap.
There are good reasons for living in cities and others for 'more rural'. Some people like the live/work combination of this. Others might prefer to work closer to home.
What chance of more employment in Fife rather than a new bridge??
