honesty and effectiveness

In our country we have smart clever and intelligent dishonest people. Then there are the honest, but not very effective people. There are of course, foolish and dishonest people.

Where are the smart, intelligent, caring and honest people ?

The clever dishonest people are too many to enumerate and also, I might get sued for defamation.

There is Anna Hazare, who could have done so much if he had better understanding of things in general, and constitution-governance-politics in particular. In short, if he had been a 'thinking' man

There is Gen Singh who could have quietly done a cleanup of the army if he had been more clever/savvy/ cunning or whatever the right word is. He could have made a precisely targeted strike and routed the enemy.

But where is an example of a caring, intelligent and effective honest man in some position of considerable power, who has achieved some cleanup action?
