A country is never corrupt, the people are. And a person who doesn't do anything to change their current state, is no less as corrupt as those who are hated for their greed and ignorance.
It is exactly was I am thinking too. It's pretty hard to change the people (impossible I could say), but it's even harder to change yourself (which actually is not that impossible, but much more important). Maybe, if we change ourselves first we can give others an exemple to follow and change themselves too.
