Re: Should Punjab carry Pakistan’s burden
There is no doubt that Punjab should try to develop all areas equitably, a lot needs to be done in South Punjab to bring it at par with other parts of the province. All of Punjab’s gas comes from Balochistan/Sindh, power from AJK and KPK and most of NFC share from Tax raised in Karachi and still some people believe that the province is bearing the load of others. 
As far as the writer is concerned, he is pointing out that the party which wins Punjab wins the country and then they focus more on the province (ignoring other three). He is making a point that they should focus on the smaller provinces as well. If Punjab is not in power (on the federal level) I think they can only try to force the federal government to work for the other provinces, but cant do much (otherwise) as it would be seen as infringing on the rights of the provinces.
