While it is a shared desire of ours as a people to have leaders with integrity it is a fact that people do not mysteriously attain integrity after becoming leaders.

What corruption does is it creates a vicious cycle which taken into the loop more and more people, and forcibly, to make ends meet, make them partisans of the corrupt system in more and more diversified varieties of corruption.
