Corruption is the common problem in many countries but you'll be surprised that it has not hindered their own growth and development as much as it has hindered the growth and development of many African countries like Nigeria that is suffering from it. The leaders of some African countries do not know when to be corrupt, they are corrupt always and concerning everything even the one that will benefit their families. The leaders from other countries in other continents where things are still going on fine are corrupt too, but selectively. They know how to be corrupt and also know that it should not be with everything, so it has not slowed down their economy.
