If people built the new towers the same as the old ones, do you know how many people would NOT want to go work there?!!?!!! Why? Because it will bring back too many memories. Working in tall famous buildings aren't good anymore. My uncles law firm has its office Trans America building, near the top, and he is nervous that they are going to be hit by terrorists if they fight back. This is not what people need, and post partum syndrome is going to be up about 1000% percent if the towers were to be built the same or bigger!
Brooklyn, Queens, Manhattan, Staten, Uptown, what now? Lets make it happen.
