Urban Development - The business centre is the showpiece of a city, as is its industrial quarter. Public space forms the essence of the city. Increased social disparity is a problem encountered by many European cities. Poorly managed public space is being overtaken by advertisements and cars and is rapidly becoming privatised. This neo-liberal concept of a city as a good, based on the principle that “you must pay to feel well in the city”, results in the segregation of people and encloses them in ghettoes: some in “luxury prisons”, e.g enclosed and monitored estates, others, in neglected high-rise estates.
