First, I shall clear that neither I have affiliation with any political party of Pakistan nor I have any soft corner for non-political leaders.
A country gets leadership from what the country has, the people. Crappy people have crappy leadership. This formula looks correct but it is not.
On an average basis, in a large group of people (like in a country); there are percentages of people who are criminals, good law-abiding citizens, religious extremists, moderates, white collar criminals, etc. etc. Hence, all sorts of people, good and bad. I hope you'll agree at least up to this part?
Same like any other country, Pakistan also have similar percentage (that I mentioned in above paragraph).
Now, saying that due to some few million criminals (all sorts of bad people) a nation of 160 million gets bad leadership just because of it? Can you name one country in this world that doesn't have criminals (white-collar criminals to street gangsters)? Just name one country!? You CAN NOT! It is not possible because it's in the nature of primates (and other advanced animals).
We get crippled leadership because in our "leadership selection system" (executive branch of government), we have checks and balances (made by previous "leaderships", political and non-political, both) that no "good" person can hold highest executive seat (i.e. PM of general assembly). From political party's checks to bradari system for voting etc. Can a "good loyal" person ever cross all these barriers and get elected to the seat of PM? Never!
Furthermore, if whole nation is bad and can never progress then why this nation progressed up to the level of 2005? Now, don't give stupid exclamation of "due to USA aid". Just think of a minute, take few minutes and read what was happening in those years of progress.
Why Pakistan got second position in cotton-based products?
Why Pakistan got second position in leather-based products?
What was happening before EU imposed anti-dumping duty on Pakistan?
Why we got progressed from extreme low of 1999 to the level of 2005?
Why Pakistan's economy was doing good when there was Asian Finical Crises?
The answer is simple, when Pakistan got good economic policies we got good results and Pakistan was progressing. When we get "crippled" economic policies, we get what we have today.
Pakistani are hardworking people. We don't have oil reserves but we know how to work with our hands. If we can make difference in first five years of 2000s then we can do it again, all we need is good economic policies by sincere leadership.
By the way, the currently government's economic policy is very simple "World should give us $100 billion dollar in aid". What a joke! Why anyone give us that much money? aa ja kar bus bheg mangna ata hai
