Peter... interesting you would be from the UK and I would use London as an example in my response above.
My Nephew's Irish father-in-law sat with us after dinner one evening and asked me wife, "Now, what would you say if you saw a man driving a BMW back home in Sacramento?"
My wife responded, "Donovan owns two of them".
After an uncomfortable pause, Aiden responded, "Here in Liverpool, you would say, 'that man is a drug dealer'."
Aiden lived through the global depression and the war and was a doctor and a frugal man. If a thread came off his jacket, he took it and wrapped it around a piece of cardboard. "Waste not want not," was his personal philosophy.
I wonder if there are possibly some cultural and generational aspects to your thesis in this piece?
