if you see pakistani elections its very clear.. punjabi won in punjab, sindhi won in sindh, pathan won in kp. but punjabi ruling country only because of higher numbr and oppressing baluchi and the rest.
Funds need to be allocated properly, as long as that is done there is no oppression.
If MQM gets their funds to develop Karachi they will, unfortunately majority government doesn't supply funds to the local party so they dont develop and hopefully lose.
