I don't think that they are the only ones that are involved in corruption however I think that it is more prominent in these countries and they are more transparent with the illegal activities that are happening as well. In other countries I think it just happens behind the scenes and not many people actually see it which could be a limiting factor in how we portray our country as well.If you can search on Google about the most corrupt countries in the world ,most of the Western countries will not be there but 90% of the countries in the list will be the African countries because they are the one that are stealing the money to the western country.
