Re: quota system and Pakistan
Antibol! You should also note that there were hardly few sindhies in Karachi before 1947. This was a majority gujrati speaking parsies' city - and all the educational institutes were under their control here except the Sindh Madarrssa. Only few Balouch muslims villages were there on the outskirts of Karachi alongside Malir, Lyari and Hub rivers.
I do not think that Karachi University closed its door for Sindhies up to 1985. In fact if we see medical and engineering colleges, there were many sindhi students back in 1970-1985. Probably Sindhi people did not prefer to take admission in KU as most of the studies over there are not job-based.
Similarly, in Institute of Chartered Accountants of Pakistan and Institute of Cost & Management Accountants of Pakistan, there are hardly few Sindhi students. These two institutes do not observe any sort of quota system.
