911 happened in 2001 and they are just starting to build where the Towers were. Two buildings, four years. I respect your optimism and NO may rebuild...but, it is going to take a very, very long time (not including a whole new levee system). Where will the trillion dollars come from?
the commercial and tourist sections will be rebuilt first. the rest of the town, the poor neighboorhoods, will be rebuilt incrementally over time with HUD money. probably $1 of construction and $9 of politcal graft for every $10 committed. its going to make the Big Dig look like a picnic.
