One needs to realize that people of Karachi are far more tolerant and freindly for Pushtoons despite presence of MQM goons and history of violence here. Pushtoons are doing jobs and business in this city with greater comfort than anyother place in Pakistan.
80% of Karachi's tranport is controlled by them (You can not think of it in other major cities of the country like Lahore and Islamabad). Fruits and vegetables whole sale market is fully controlled by them. At least 30-40% of the resturants are owned by them. Most tandoor and tea stalls are owned by them.
You wont find a non-pushtoon shop in Karachi's areas like Frontier Colony, Bacha Khan Chowk, Patel Para, Dawood Chowrangi, etc. But you can find pushtoons doing all sorts of jobs in other parts of the city - even in the stronghold of MQM - Azizabad - here you can see tandoor, tea stall and fruit sellers etc beside pushtoon rickshaw drivers.
yaar, whom you are trying to tell have pre-set mind and have no ability to think. They are famous group of people living in mental syndrome of 'may na manoo'. Many of them are racist too, with full of hate as they are aggrieved that they have to leave their province to find work and opportunity in Karachi. Well, some are representing pathetic leaders of Punjab and Sarhad and do not like their incompetency to get blamed for the misery of these migrant workers, so they have to find baseless excuses and escape goats in others.
Very few people may know that Sindh before 1947 was much less developed than Punjab and Sarhad. It is hard work and only hard work of people that made Sindh what it is today. Present Sindh is magnet for most Pakistanis looking for jobs and opportunities. Why?
Fact is that what people of Sarhad need is to ask 'Syed Mustafa Kamal' to become Chief Minister of Sarhad with full power and cooperation from all. If that would happen than Sarhad would experience unprecedented development in all sectors as there is no shortage of anything in Sarhad and Sarhad only needs good hard working intelligent person as manager with vision and desire for progress (like Syed Mustafa Kamal). Consequently, People of Sarhad would get good education and will be well provided with amenities, infrastructure and plenty of job opportunities. In such situation, Sarhad would become magnet for workers from all over Pakistan, including Punjab.
But then corrupt leaders of Sarhad would never like that, as for them, their pathetic leadership could only survive when Sarhad stays deprived of prosperity, progress and development. These pathetic leaders want uneducated and gullible masses of Sarhad to stay misguided, keep believing that these crook leaders are doing everything best for them, and never ask question. These leaders want people of Sarhad to keep becoming non-resident labourers in Karachi and other places far from their home, and keep dying for their thug leaders (be they religious or secular), without a word.
Unfortunately, innocent people of Sarhad could not understand that there is big difference between migration for conscious (religion, political beliefs, principles, etc) and migration for needs (jobs, education, amenities, calamities, etc). Masses of Sarhad (and to extend Punjab) never ask their leaders that why they are in such pathetic disgusting situation that they have to move out of their province to Sindh (Karachi) for lowly jobs, good education, basic amenities and opportunities. Why all these necessity of life are not for them in their province?
Obviously, these pathetic thug leaders of Sarhad keep giving lip service and hoodwinking misguided masses of Sarhad by blaming others for their misery and lack of opportunities, creating friction wherever these innocent people go for work. These pathetic leaders never tell these innocent people that their problems is not due to others but their main problem is they themselves as they chose crook and incompetent leaders, else they could have got their paradise without becoming migrant labourers far aawy from their province.
[Believe me, I really care for hard working Pakthuns and my family helped many Pakhtuns to find accommodation and job in Karachi. My brother opened his first medical clinic in Bararas colony where he was giving free medical service and medicine to poor Pakhtun (and Afghan). At my family house servant quarter our Pakhtun chokidar provided free accommodation to many of his relatives (with permission) before they found their own accommodation. My uncle when retired from service brought with him 2 to 3 families from Punjab to live in his servant quarters and later when their family expanded, one of the guy with his family moved to our house and we not only helped him financially but helped his family in every way, providing free medical care and medicine plus money whenever they needed ... actually, there are many instances that we helped or tried to help others, without even thinking of their ethnicity].
