I voted for pti, like a lot of karachiites but nothing can change until they get hold of the federal and provincial govts
If PMLN wants to a shut mqm out then they should do something for Karachi like a subway system or multi-route metro bus, , best way to end 'muhajirsm' is to abolish the quota system which discriminates against urban Sindh (Karachi,Hyderabad & Sukkur), that would takeaway mqms last card.
Maybe fed govt could go a little forward and hand over the businesses owned by karachiite businessmen that were nationalized by Bhutto, that would be a final nail in the coffin, before the 1980s there was no such thing as MQM, let's go back to those days
One more thing that could end MQM is by recruiting police officers from local karachiites instead of transplanting officers from interior Sindh,Kpk,Punjab and the like.
Until locals don't get involved in policing then crime can't be eradicated and the citizens of khi won't trust the police, it's like expecting an African american to trust white police officers in detroit
