The one thing apparent from recent election and Win by PTI is even , after the win it was difficult to change Sindh as it is still ruled by Ethnic Politicians. Government was forced to allocate almost 10 Billion Dollars to Sindh Government (regional government) even knowing they do not have ability to develop Karachi
Thus it makes more sense to adopt a more Presidential System similar to US where the winner takes full control of Federal and Provincial matters and he "Chooses" his favorites for the role
How the winner President Chooses his team ?
a) Freedom to Choose one of his political affiliates for role for Ministry
b) Ability to hire a PHD or expert from Pakistani Origin for Technical Purpose no prior political experience required
c) Freedom to distribute budget to his team members at will
d) No interference from Regional Provincial politics
e) Any citizen of Pakistan can be assigned in leadership role in different provinces
