Every country. Even those rich countries have a lot of corruption and if they didn’t have any corruption they could be richer I am sure. My country for example would be a lot better if the government worked efficiently the way that it should and we took less time cleaning up the mess politicians are always leaving behind.
My country is also not exempted from this; there are more corrupt politicians and government officials than the good ones with pure intentions for the country and its citizens. They are more focused on what they can do for themselves while they are in office over how they can better the country's condition, and until such people with that negative mindset don't have a place in politics, it will be hard for such a country to grow economically.
