Re: Memons
Just to add some pride to the memon thread 
Companies like the following are run by memons (or at least were started by memons - I don’t know if some have been sold):
Pakola
Pak Towers in Karachi - owned and built by people I know
Rangoon Wala charities
Eidhi charities/social work
there are some other biggies that I’m not sure about names, exactly. I think there is a bank (maybe Habib, not sure); a massive insurance company (can’t recall the name); multiple construction companies operating out of Karachi ; a soap or detergent company (one of our in-laws is involved in it - don’t know the name).
And then we have lots of people in entertainment. Abdullah Kadwani - who runs a production company with Humayun Saeed. I had a great-uncle who produced a few movies and introduced Mohammed Ali into the showbusiness, back in the day. And another one of my great uncle’s was the architect of one of the major civil buildings in Karachi - some judicial/municipal building - I remember it has some domes. I don’t know the name.
Stuff like that. We’re an enterprising group, yo. Its all about figuring out the most efficient way to earn a buck.
