Some are, but not all. The point here is building entire towns or entire new city sectors in one fell swoop instead of planning them out and building them in stages so plans can be adjusted as needs inevitably change is a bad idea. It's things like this that have directly led to the current property market crisis.
Of course if buildings are already there it makes sense to use them, but they might have been able to put something better suited or more economically viable there if they had staggered the construction.
And yet somehow the head office with total power is hereditary just like a monarchy.
