Bed time stories by elders are most of time exaggerated. It's not difficult to find out if someone is interested in truth rather than living in delusion. This is non-Pakistani source
However, it is usually quite easy to manipulate the information that is actually available. For example by deliberately picking and choosing passages and ignoring the actual facts.
Meanwhile, other communities already had a lingering sense of Mohajirs having far more prominence and power than their numbers deserved. Pakistan's indigenous communities including the Punjabi, Pashtun and Sindhi's who's literacy rates began rising, naturally represented more than 80% of the countries population but until the late 1960s, almost three quarters of the bureaucracy were still being held by the former refugees. Mohajir's also unfairly favoured hiring of people from within their own community over people's indigenous to Pakistan and often invited distant relatives from India to fill these spots over hiring of local peoples, this policy further increased resentment against these formerly welcomed refugees.

It wasn't strange that you chose not to find a complete and comprehensive source and posted unverified and unconfirmed stats and that too only from this side, discounting the massive involvement of Mohajirs in West Pakistan (such as Biharis).
There are 100s of books and research papers on Punjab's domination if you are interested.
Punjabi's have dominated the country ever since its creation, but that was not on merit, it was on sheer politics and power of population.
I got the point - that Urdu Speakers are some sort of superior race with whom dumb Punjabis can't compete on merit
That's not the point, you misunderstood and took it personally.
On merit, Urdu speaking would take up a lot more seats in the bureaucracy and other government positions simply because we are more educated over all. On merit, the breakup most likely would be 40-45% Karachi and Punjab (each), 10% Baluchistan and maybe just about 5% Sindh. You know what the reason for this is? Ask any of your Urdu speaking friend how much his parents spend on his education and/or how much he spends on the education of his/her children. The education of our children is a major chunk of our household income, as a community. We invest heavily in eduction which is not rivalled by other ethnicities on the same %.
Again - cooked up stats & facts. But yeah, we dumb Punjabis can't compete with superior Urdu speakers that's why we asked Sindhi feudal to allocate quota to us.
Cooked up stats??? Seriously dude, that's the best you can do? Do some research.
You know what - it's people like you who will always keep whining no matter what. If after removal of Quota Punjabis ends up with more job than you will be crying that merit was not followed, because you live in delusion where all other are dumb.
I know for a fact what would happen to the bureaucracy if the quota system is revoked. No wonder your Government has vetted and expanded the quota system for another 20 years.
In any case, let everyone cry but support merit.....it is for the better of the country and for the better of our next generation. It is also better, overall, for cohesion and unity besides better management and competent decision making.
