Yes that's what I was worried about too. Somthing like the Soviet buildings. That's why I "came up" with the idea of those locations having their own ecosystem. Meaning not just homes but also jobs are provided and they would ofcourse have police, clinics, and fire stations. Which would provide when more jobs.
I believe if you keep the people busy and they have a way of earning income then no sane person would dive into crime. The reason why those places you mentioned are ghettos is because they people have no jobs. They are discriminated and jobless, ofcourse that would kick in the survival of the fittest feelings. Which makes them do anything they can to provide food on the table.
At the end of the say we do what we do to feed yourself and provide a roof over our head. Look around you and that's what everyone is doing. No matter what kinda fancy name you give it.
That's why I believe the ghetto situation would be avoided by encouraging that ecosystem.
Here is what I have in mind. This is based on top of one of the slums near the port. Getting rid of this would greatly improve the image of the city in that area.
Green===parks near the water
Blue ===mid/high rise appartments
Red====main roads where most commerce would be based.
I didnt fill the whole map but I believe everyone gets the idea. The sad part is that soeul was based on Karachi and now we are talking about basing Karachi on soeul.

Btw this whole plan is based on the idea that Karachi is under competent governance and not PPP, MQM etc.
I wish Karachi to be the Tokyo of south Asia and middle east.
