If people of Non punjabi descent like Nawaz Sharif can benefit from invesments in Punjab, it only shows that punjabis are a welcoming bunch who ARENT prejudice towards outsiders. Otherwise, how could Nawaz Sharifs family have succeeded in Punjab? This in no way means that Punjabis are trying to dominate anyone.
One the contrary, it shows that Punjabis are open to non Punjabis..
