But certainly you don't develop either with having a team of corrupt businessmen and money launderers running your country.
I think you are naive to the reality.
In idealistic world, no, but in real world, they do thrive despite of corruption, money laundering, tax evasion. In fact, the world also has the same problems. But as long as investments continue, and so will the world.
In realistic world:
A) Corrupt leaders don't wanna invest on Pakistan to build economical progressive society
B) Corrupter leaders [marginal or extreme] invests on Pakistan to build economical progressive society and has long-term vision to build
C) Non-Corrupt leader is yet to be discovered, although some claim to be non-corrupt judging by advertising in social media having been exposed to public on lack of economical visions for Pakistan while desperately trying to paint Pakistan as chaos nation through many tactics including issuing civil disobedience to derail the hard work progress built by people with hard-earned money to improvise the already-struggling economy of Pakistan. A self-claimed Non-Corrupt with empty rhetoric dialogues with nothing practical solution to offer except to get married
D) Non-Corrupt leader with long-term economical visions for Pakistan aka awaiting prophesied Danday Wali Sarkar in according many people in the past.
Pakistan has already dealt with A, but now replaced by B as we can witness numerous billion dollars projects involving energy, highways and more. Not to mention, Zarb-e-Azb mission against TTP and MQM Headquarter mission within in five years of PMLN government while apologetic party wanted to legalize TTP by encouraging governments, Zardari/Gillani in 2010 back then, to open the offices for TTP and sought the support of MQM for dharna recently.
I am less confident about C judging by progression in Peshawar, but that being said, i have faith on option D and B than C.
