The summary of the document is: 1) The rebuilding of Ground Zero is progressing slowly while New Orleans has made more progress in rebuilding from Hurricane Katrina despite facing greater devastation. 2) Negotiations between Larry Silverstein and the Port Authority over the redevelopment of Ground Zero have stalled again over issues like rent and insurance proceeds allocation, though some progress has been made. 3) The author argues that claims of greed against Silverstein are misplaced and that the security and construction challenges of rebuilding at Ground Zero will necessarily make it more expensive than typical buildings.
