Re: quota system and Pakistan
Let's gather Public + private sector jobs and see the ratio of each ethnicity. I am confident that my community of Urdu Speaking will have the lion's share only seconded by Punjab. After that are just guess-timates (due to lack of data). Anecdotal evidence will most likely show Sarhad at #3, Sindh #4, and Balochis at #5.
Well dear things have changed a lot. Even in my company, which is located in Karachi we have about 60% urdu speaking people (including memons) and 40% people original Pakistanies.
