They are the work of the past. PMLN came at the time when the nation situation was already digressed, load shedding everywhere.
You should be blaming Marshall Law. Same Marshall Law that cost Pakistan from thriving economy under democracy in 50s went down to become unpopular nation with economy went down the drain in 70s. Then the economy got stabilized little while under democracy, and the military takeover in 80 and the rest of history to this day Pakistan is still dealing with side-effects of 80s policy.
90 was stable under the democracy, then military happened aka Musharraf. Then Pakistan became unstable nation very fast with allowing MQM to devour every resources in Karachi and allowed the birth of TTP. Bad receipts for the economy which resulted in killing non-stop and effected economy big time which brought poverty and whatnot.
Democracy just got back. The situation is starting to stabilize, and improved a lot compared to the last five to ten years. As i said earlier, it is gonna take more than 15 years to correct the mistakes had been done by the military leader with no concept of economy. Good news is that with the recent waves of billion dollars investment on the energy sectors, CPEC, and many other pipelines joining, they might fast-track Pakistan to become one of the stable nation with thriving economy in the near future only if democracy completes its term with peacefully.
It is important to let the democracy completes its term as sign of faith that a nation can be trusted with major investments. Stable democracy is the good signs means it is safe to invest in. Unfortunately, we still have PTI who are determined to undermine PMLN at the expense of Pakistan. I have no problem with PTI maintaining anti-PMLN, but not at the expense of Pakistan. Last Dharna cost Pakistan more than 500 billion rupees, burned infrastructures, took cities and towns as hostages, forcibly closed the businesses of cities and towns, imposed ban on the traffic which means no transportation - in other words, disasters for the businesses, and almost brought military takeover. None of the signs exactly echo that it is safe to invest with their money. On the top of it, those are the signs of anarchism which suggests Imran Khan is being anarchist big time.
Right now, he is inviting every anti-Pakistani elements to join Islamabad lockdown including some pro-TTP. That is literally advertising to the worlds that don't invest on us. There is the reason why General Raheel agreed to work with Nawaz Sharif, not because he wanted to, rather he had to for the sake of the stability of politically and economically. Both don't get along but when it comes to bigger picture, they are on board together. For how long is the question considering General Raheel is retiring too soon and some unfriendly Generals are eying for the military takeover under the excuses like Islamabad lockdown and dharna in the past aborted. I think PMLN might run away before the democracy completes its term. If that happens while military takeover, then it is over. No bigger players would invest their money on the unstable democracy hijacked by the Marshall Law that is literally anti-thesis of economy.
Enjoy democracy while you can. Democracy ruled only considerate period of time compared to the Military law. Once again, the democracy is likely to meet its demise sooner than we think.
