I think this post is exactly the type of post that could use a little more of what Tyler Cowen dubs "anthropology of ideology" - not to mention a refresher course in grammar and writing.
Unfortunately, what research we do have has been unable to find the true causal mechanisms to what is shaping up to be one of America's most vexing urban problems. It is somewhat unclear whether the new residents were full douche bags before they arrived, or whether they were transformed into douche bags upon moving into their new abodes. Is douchebagness produced by the local environment? Do the handful of non douche bag residents run the risk of becoming douche bags do to increased exposure to small dogs, overpriced handbags and DINKs? Or are douche bags somehow integral to the production of new urban space? As cities slowly but surely rezone every inch of waterfront land for high rise condos in the hoping of luring the Richard Florida Fan Club, a massive influx of complete, utter, quasi and mega class douche bags to what may have once been somewhat interesting, gritty or real places is inevitable.
What is it about our time and technology which has seemingly enabled and encouraged people to disseminate such gibberish? When did it become OK to publish unsolicited opinion with out so much as looking at data or collecting a single solitary fact? My sense is this is worse in urban planning related matters than in most other fields, but that may simply be because it's my field.
