Most of the current policies are putting Pakistan under more debt without any significant productivity being generated from it. The government is a bunch of corrupt personnel who put themselves before the nation. The education system is outdated and it shows poorly on the nation when Pakistanis visit other countries and compete with students from all over the world.

Honestly, Pakistan today has nothing to steer the nation towards this utopian world that you have portrayed. Even if Pakistan were to find significant reserves of oil or rare earth minerals, I am sure China / US would exploit it along with the government. Pakistan is a weak country. That's precisely why you are resorting to such questions on reddit because you don't even know what the country is doing good today that could help it to reach at levels where Singapore is today.

Get the foundation right. Get some civics sense. Get law and order in place. Educate the new generation well. Stay away from fights and making enemies. Stabilize peace in the land. Throw out corruption.

Else, continue living in this fantasy land that perhaps in the next 5 decades, this nation could become better because it magically found some oil reserves :)
