In my opinion, i think the quota will be implemented in2 or 3 years. Dont wait.
Punjabis in the federal bureaucracy dont want any outsiders.
If i say that Pakistan is about punjab exploiting the rest of the three provinces, then i m not wrong.
One example is, when east pakistan was still not independent. It insisted on population as the main base of distributing federal resource pool while punjab said no. Punjabis said that area and backwardness should be the criteria. Punjabis won. But they lost east pakistan.
Now punjabis want to lose balochistan. They dont want to give balochis there fair share even on the basis of population. The 1998 census showed that balochistan had 5 percent of the whole population of pakistan. The quota should have been increases automatically. But Alas, our so called muslim brothers Punjabis withheld our share. Our so called mussalman brothers will exploit balochis till they are exhausted.

I think punjab will also lose balochistan also, very soon
