I view Pakistan's problem as a political one, whereby the decision-making is seriously compromised because of competing interests. What we see currently unfolding in Pakistan is the classic Civ-Mil tussle that has been the bane of Pakistan since '50s. After having worked in textile manufacturing for many years, I am currently working in Retail, at Head Office of one of the largest retail networks in Pakistan. I can not overstate how the political instability - mostly induced - plays havoc with economy. Consumer-driven economic activity is sentiment-based. Cynicism & pessimism negatively affects an economy, while optimism buoys it. Take a look around in Pakistan. Cynicism sells and many political players are doing a good job of encashing it. To me, that makes a big difference. Pakistanis have a phenomenal ability to face and out-last adversity. But that strength seems to be sapped by loud rhetoric that aims at preserving entrenched power structures.
Bangladeshi nation has found a way to protect its core economic interests from occasional instability. Garment industry provides incentives and proactively anticipates how a 'hortal' may affect their production and ability to meet export orders. Political parties too are mind-ful of not hurting export of textiles. I am quite sure that Chittagong does not have a MQM style extortionist party. The military too does not actively play politics. There is no Indian-sponsored instability in Bangladesh. There is general peace and stability and foreign buyers like to place orders in Bangladesh. With all these factors working in Bangladesh's favor, it is no accident that Bangladesh beats Pakistan in GDP growth, Exports, Human-Development Indicators, & perception.
Pakistan on the other hand is marred by obsession with security, weak governments (even when they come in with big majorities), civ-mil tussle, agencies that operate without any civilian over-sight, terrorism, perception of poor law & order, in addition to all other issues pointed out by other posters.
China, India, and Bangladesh have grown despite pervasive corruption. Pakistan could too. But then corruption is an excuse to beat civilian governments. The civilian faces driving the anti-corruption campaign are themselves compromised and look to the military for favors. The day civilians achieve ascendancy would be a good day for Pakistan. Security mind-set inevitably weakens the nation while strengthening the state. Pakistan has just about had enough of it by now. Pakistan needs to set its house in order, find ways to make peace with neighbors, & focus on internal development.
