Can we stamp out corruption only by punishment? Well we have to unearth the root cause. We can't expect peaches to fall from an apple tree as once said by Master Oogway (Fictitious Character who was Masters in Wisdom). We get what we Plant.
-> A victim of financially depressed milieu leads to Insecurity within him to get more and when the question comes through any mode, u hear kaboom of corruption.
-> The Greed of a well-heeled to come into fortune 100; and
-> Fear of losing whatever has been accumulated.
we annihilate these three causes, and we'll have a good clean system.
