Three times in the past month, The Sydney Morning Herald, the city’s broadsheet of record by default, has published a particularly irritating kind of article on urban density. To paraphrase Paul Thomas Anderson’s Magnolia (1999), this is not just a matter of chance. These articles, by the paper’s two resident economists and sole architecture critic, represent a disturbing and powerful tendency to treat cities as economic entities, blobs on a map rather than physical spaces. They don’t realize that you can’t extrude spreadsheets into skyscrapers. Help! The Borg economists are eating Sydney.
