And those things can change, suddenly having a huge tower in downtown NY becomes a sign of a out-of-date "old" company; perhaps the new hotness will be something like a small company "town" in the outskirts somewhere.
So the "new hotness" will be kind of like the old days where you worked for Pullman, and with those wages you earned, you: paid rent to Pullman, bought your goods at the Pullman general store, and so on in effect giving much of your earnings back to the company.
Cities too. My city government offices are located on some of the best real-estate in the city and in elegantly refurbished turn of the century buildings.
Government offices should be pre-fab cheap as possible in brownfields or on other low-value land. High value land should be used for at minimum something that will generate property tax revenue.
You should realize that the real estate around the government offices in your city are high value because they were located near the government offices?
