I had brought up the point that the WTC was not 100 percent occupied for I had saw a documentory about the WTC in 2004. It was reported in the film that Morgan Stanley and some other firm took up about four to six floors of the WTC and the building was only 3/4 occupied with tenants. I was also saying that reading the blogs from different people I feel that Detroit was very practical in not building any high rise during the 20's or 70's. We have more land than Manhattan to stretch out many buildings. Another person had said that the RenCen didn't have to be as tall as it is. Back in the 70's detroit was showing signs of decline and didn't need the office space.
