quirky, when you mention working classes being paid by the week, are you talking in the present?
I don't know the ultimate answer either, realistically there probably isn't one absolute one. I'm always inclined to explore the macro view. Within Dutch architectural and (urban) planning education sociology is very much interwoven, and there's a lot of emphasis that we understand that the environments we create influence the users immensely, so pursuing architecture solely on aesthetics is a terrible (but often made) choice when all it serves is the architect's ego.
I agree, it's very Parissienne to discuss all sorts of subjects. Perhaps we should rebrand ourselves as a very pretentious Salon 
So, onto philosophy, "I shop, therefore I am" 
Thanks for the HP piece, btw, quirky. It was a long but very interesting read, if a bit disheartening.
bob, I've always wondered what anthropologists make of MN. Surely it must get you itching to document it all... Admittedly, as much as this place is a distraction/mindless chatter kind of place for me, it does enrich my professional life to have such insight into so many layers of society.
