My interactions with our Parsi countrymen tell a different story.
They are shocked at the lower middle class poverty of their Indian brethren ( the three billionaires not withstanding ) living in ancient crumbling houses with 19th century furniture, completely culturally isolated and overwhelmed with the rising Maratha sub-nationalism and mafia harassment.
They told me the movie Mr. Pestonjee was very real. After the Anglo Indians the Indian Parsis are the next to go and fade away into the twilight.
There is no comparison between their lifestyles in Karachi with their chauffeurs, armed guards, housemaids, cooks and commercial urban property as well as lavish sprawling homes in the boulevards of Lalazar. Yes, their community was smaller but they enjoyed the inheritance of business empires, prime urban property and financial security way more than any of their Indian counterparts could dream of. Which is why the Dar-e-Meher Agyari in Karachi matches its Bombay counterpart in splendor even with a population a fraction of the community over there.
No Parsi in Pakistan goes looking for a job. It is all there in their inheritance.
