The river never drinks its own water.
The tree never tastes its own fruit.
The field never consumes its own harvest.

They selflessly strive for the well-being of all those around them. Do our leaders of today understands this.

Obviously not.

Will that day come when it will happen? Yes. It is possible only when the people demand. Government or the present political system is corrupt because people of Pakistan tolerate. If the nation does not accept  the prevailing situation of corruption there is no way it will continue.

The basic problem is the people of Pakistan think that this is the responsibility of their leaders to change their conditions for the better. And the leaders have decided to use the national resources for their person benefit. All politicians are agreed among themselves so nothing will happen anything good for the people.
