I relocated to Karachi after 12 years and lived there for 4 years before immigrating back.
I was shocked by the change in demographics .The city is a giant ghetto.
There is a clash of civilisations going on in cities. Neanderthals are competing and sharing public space with cosmopolitan, urbanised classes. This is bound to be a clash of values. On one hand you have scum of the earth, abused, neglected,scarred souls mixing living space with 'normals'. Unequal animals do not live together in jungles, they roam together in packs and only go close to the other animals when they have to prey.
