That's the story of every city, it does not say how big of an area this tower serviced but I would guess that the area was dense and expensive enough. Also the company that built this went on to merge with Ericsson which managed quite well in the telephony area. A big part was that they managed to deliver telephony subscripions to so many people so fast, Stockholm was way a head of e.g. London (20x) counting telephones per capita. There are several reasons for this the comming population explosion that created the slums you talk about was one. During the period this tower was needed the population of Stockholm more than doubled so how the slums where distributed will most probably have changed during this time.
