Read this. From it:

Rather, critique is a process that is at the very heart of the urbanization of everyday life. In fact, pushed farther, critique can be proposed as a return to life through the attempt to “open a path to the possible” by an investigation of what negates the possible. ...

These two powerful themes of our times are sustainability and creativity. When these themes are not grounded in equity and justice, they become programs for the city and extensions of the new spirit of capitalism’s answer to the artistic critique of urban life. That is, worse than policy fixes dropped down from above, shined up at “stake-holder” discussions, and then implemented in the grandest modernist fashion (and setting off uneven development within cities between the creative sectors and the working-class sectors or the sustainable areas and the inefficient and often more-affordable areas), these terms signal a startling reversal of powerful points of critique.
