There is an interesting area near the airport that has been taken over by poor people. It initially was a large empty field. Poor people came in and began building ramshackle housing out of any materials they could find. Once the land was completely filled, they started building up with unreinforced brick apartment complexes. Because of the recent (30 years ago) heavy-handed and oppressive military government, the current government will not forcibly remove them. The only leverage the government had was to limit the amount of building materials that were available. But as you know, people find a way to survive. These slums are in the heart of the city and cast a onerous spell on the middle-class communities surrounding them.
