I could be wrong but Pakistan’s elites are in the following cities:
Islamabad is the home to the political & bureaucratic elite. Very chaste and crisp Urdu and a real redoubt of the Pakistani government. I spent alot of time in this city when growing up but have found to be a Talibanised version of an English village (I jest but not by much). The main ethnicities are Punjabis, who are thoroughly Urdufied and Pakistanised and Pathans, who are the exotic minority in the city with their colourful language & weird accents.
Pindi (Rawal) is the ugly older sister of Islamabad but of course is where the military is based and so would probably be where all the military elite (which is the shadow government of the country) is based.
Lahore is the home to the economic elite, after all Punjab is the largest and most influential state. It is no Karachi however and is far more regional than cosmopolitan. It has a rough macho culture and can be a bit crude & crass. However as one of Pakistan’s oldest and most prestigious cities it has considerable sway. Punjabi language & ethnicity has obviously a strong sway here as the common tongue mixed in with Urdu of course.
Pakistan’s greatest city (& my personal favorite) is of course Karachi. It may not necessarily have the moneyed but the social trendsetters are here . Predominantly drawn from Pakistan’s once dominant elite (the Urdu-speakers are sort of like the Wasps in Pakistan, a faded elite) who go to certain schools (well only one, KGS), study abroad, live in Defence & Clifton and have a rather hedonistic approach to life (not in the manic way as upper-crust Lahoris but in a more studied & sophisticated way). The living room arbiters of the cultural life of the nation; English-speakers with Muhajir heritage (of course most of these families have intermarried with the locals etc). Love-hate relationship with India and very confused about Pakistan in general; believe that they are the last continuance of the Mughal decadence of Delhite culture. I may be projecting my own love of Karachi here but it really is the Queen of East; the last redoubt of Urdustan.
Much as I like New Delhi (I much prefer New Delhi to Lahore & my truest roots are there since my late grandmother was born in Karol Bagh) it’s not very inspiring to see the Muslims clustered in ghettos like cattle waiting to be slaughtered. Ghalib would probably find Karachi, more than Delhi, to be a more familiar city..
