Nah....they good. CPEC will make them rich not to mention America pays them a lot to allow drone strikes. Just google how much aid America gave them in last decade. That's why their whole country trembled after Trump tweeted about them. They will either force themselves on America or China claiming to be their best buddy.
CPEC cannot make anyone but a small state of a few million people rich. You forget that Pakistan has an enormous population of 200 million that is growing at 2% a year. It needs major political and economic reform in order to grow GDP/capita at least 5-6% a year(it is currently at just over 3% with BD at 6%), and it has never grown at these rates sustained in it's whole 7 decades of independence. CPEC will certainly help the Pakistan economy for sure but it is not a magic wand to transform Pakistan into another Japan.
Pakistan has has 2 decades of subsidies from BD in the 1950s and 1960s with fiscal transfers, and one decade of it in the 1980s with US for Soviet invasion of Afghanistan, and yet BD has just surpassed them in GDP/capita. I am discounting the last decade and a half as what it got from the US, it lost in terrorism etc.
