That's totally true as well. I didn't even think of that last night. People often think Asian megacities or US megacities as the most expensive. But that's not true. It's actually cities in Africa.

I guess another valid point is the problems African cities are dealing with are sort of indicative of what's projected that most mega cities will deal with in future. A huge income gap, lots of overcrowding and some kind of constant security and resource problems.
