I disagree with due respect. This is the beauty of the "SYSTEM" that I keep writing about. In about next 10 years, you'll see a shift. What would happen is, the Zardari's, the Bhutto's and all of the world, will remain involve in politics. But their kids won't be the "chosen ones" to be the PM. That's how the system changes itself.
I hope you are right and that is what happens in next couple of decades, but sadly that's not how things work in this part of the world.
We can argue that because democracy was not given enough time in Pakistan the system was not able to correct itself. But if you look at neighboring India, they have pretty matured democratic system in place, but still one of the two major parties of India is actually controlled by a single family, Gandhis (or Nehrus) for the last 67 years.
Similarly in Pakistan its Benazir after ZA Bhutto and Zardari after Benazir, surely Bilawal or Asifa will be the new leaders of the PPP.
Same is the case with PMLN, look at the name of the party its (Pakistan Muslim Leauge Nawaz), it is a family run party with two brothers at the helm of the country and its biggest province, the finance minister is father in Law of Nawaz Sharif’s Daughter, the minister of power is nephew of Nawaz's wife and so on. Hamza, son of Shabaz Sharif is the defacto chief minister of Punjab and Maryam daughter of Nawaz was sitting as a chairman on a RS 100 Billion Fund without holding any legal authority.
This is the political environment of Pakistan that we are talking about and in many ways its worse than India.
There is no such thing as ideological politics in Pakistan. In US you know Republicans are conservative and Democrats are liberal, in UK Torries are conservative and Labor liberal, in India Congress is considered liberal while BJP as right wing conservative. There is no such distinction left in Pakistan, people no longer vote for ideology, in fact all of the major parties in Pakistan look the same to a neutral observer. People vote for personalities, these parties are nothing more than personality cults.
Don't expect Nawaz, Zardari, Hamza, Bilawal to stand in a presidential debate kind of forum and discuss Pakistan's problems, they know they can't and they will never allow such a thing to happen so people can judge them. In last elections local channels tried to arrange such a thing and they all sent some of their touts to speak on their behalf. They are cunning and they will never expose themselves like Imran Khan did in the last year dharna, he talked a lot instead of just reading a written speech and lost a lot of credibility because of some non-sense remarks. And believe me he did a lot better than what we can expect from Nawaz or Zardari if they have to speak without a written script. So no presidential debate style of debates in Pakistan for the next 50 years.
Regarding your comments that slowly democracy will come within the party and this family politics will end or otherwise these parties will break. Again that would have been the case in many other countries but not in Pakistan. General populace of this country is extremely loyal to either Shariff or Bhutto family, and their party members know that, so there will be no wholesale defections.
It is said that Chaudary Nisar was promised the CM ship of Punjab by Shariffs before the previous election but was latter denied of the post and that's the reason why he is upset with them but still he knows that if he leaves them he will end up like Sheikh Rashid, so he is sticking along. Any body who aspires to be a PM or a CM of Punjab province for that matter will be seen as threat by the family and will be removed or sidelined. Its kind of political mafia.
Of course we can see PMs like Geelani or Pervaiz Ashraf who were from outside the family, but we all know they were not running the show, Zardari was. And that was also because Bilawal was too young to become a MNA and a PM.
So i don't think anything is gonna change in the next 15 years, i did not vote for IK but i actually hoped that he will change things but it seems that hope is lost too.
