The Mubarak government extended a series of policies initiated under  Anwar Sadat. The regime supported laws and actions that sharply limited  Egyptians’ access to public space — to places where citizens could  congregate, meet, talk, interact. It promoted the development of gated communities with  private parks, golf courses and luxury shopping malls, and in doing so  facilitated the exodus of Cairo’s middle and upper classes into the  desert at the city's periphery. At the same time the government ignored  the city's center; its ongoing mismanagement of housing development has  resulted in the extensive zone of informal housing, mostly unfinished  brick shanties, that rings Cairo. And Mubarek worked to effectively  dismantle and depopulate Cairo’s much-admired public squares and parks,  including not just Tahrir Square but also Ramses Square and Azbakiyya  Gardens. For decades, in fact, public policy and urban planning, like  most governmental matters, were filtered through the harsh lens of state  security. Urban open spaces  — anywhere citizens might congregate and  stage political demonstrations — were systematically subdivided or  fenced off or given over to  vehicular traffic and flyovers, and thus  made challenging and even scary for pedestrians. Collectively such  policies have led not only to the decline of public space but also to  the inexorable deterioration of cities and the erosion of civic pride.
