I wonder if they plan their buildings with the idea that some day they might be more or less easily turned into schools, apartments, hospitals, etc.
I can see them build a little-town atmosphere. It would feel more cozy and cultish. It would be easier to attract the last-stand JW's when there is only a handful left or it could be sold to some investers that want to build a huge outlet mall and need a town nearby for the employees.
Hey, it's probably been mentioned (as I didn't read all the entries) but not only will they make profit from sales, but they will tell the members that they need money to build the new HQ and volunteers to come out for weeks or even months at no pay before they pat them on the back and send them home with the great honor of having met and housed the Governing Body.
