New Delhi is proving itself to be incapable of sorting out its own regional disparity issues, in this light what and how can you expect Indian Government to intervene in similar affairs of other countries.
The best bet for the people & their representatives of the oppressed regions within Pakistan is to make a case and present it to the Western Governments - perhaps to the British Parliament or to a Turkish Parliament (as a counter weight), and NOT to the United States by the way! - so immeture to solve any problem seriously.
The other thing to do is probably cooperate with the newcomers - why are the Punjabis so powerful, because they lived in Punjab - in a rich land of 5 rivers! if the unfortunate party can win their hearts - probably they can share the wealth and move toward prosperity. The world is moving toward a faster, and better communications systems day by day. So it will be unthinkable in future to expect the people separated by a few hundred miles to be culturally as different as they were a 50 years ago. Also, it is extremely difficult to stop the influx of people in general, and if they are rich and powerful - your only weapon is to cooperate with them! (with utmost humility - without expecting even a sweeper job in their enterprise!). Assimilation is a long and arduous process.
