From The American:
"Ultimately, in good times or bad, cities have to want a middle class to have one. And politicians, if asked, will genuflect to the idea of maintaining a middle class, yet their actions—on taxes, regulations, schools, development—suggest otherwise.
Indeed, in reality most urban areas have focused on creating what New York Mayor Michael Bloomberg famously dubbed the “luxury city.” To pay for often inflated public employee costs, the luxury city can only survive off the wealthy and on other groups—empty nesters, singles and students—who demand relatively little in the way of basic services like schools and public health facilities.
City planners and urban developers favor the unattached: the “young and restless,” the “creative class,” and the so-called “yuspie”—the young urban single professional. Champions of the unattached suggest that companies and cities should capture this segment, described by one as “the dream demographic,” if they wish to inhabit the top tiers of the economic food chain."
