If you want to truly eradicate the chains of corruption in a country, the role of the president alone will not be strong enough to succeed. Because, it is possible that many of the President's subordinates are conspiring to commit corruption (ministers, council members, and so on). Therefore, to break the chain of corruption, solidarity and firmness are needed from all levels of government and society. Because if you only rely on one president, I don't think you will be able to do it. Therefore, solidarity must be implemented.
Corruption is her to stay and we should not even think for eradicating it because we all are humans. We can reduce it be we cants stop it finally. There are people that are born in corruption and they can't depart from it because they live and abide by it..
This is why their are sufferings and unemployment everywhere because the government of many countries are corrupt and not ready to do what will make their citizens to have a good life and live comfortably.
