It seems to me that corruption is the main problem of mankind, and not of individual countries. To some extent this problem exists everywhere. But it is impossible to eradicate it, because corrupt officials themselves and they do not find themselves.
No country is corruption free, but you can always eliminate the corrupted officials/law enforcement and get a much less corrupted country.
Yeah you are so damn right there is absolutely no country that is free from corruption,
And eliminating the corrupted officials is so damn hard to do,
But I hope in the future we could live and see some country to be free from corruption it seems hard but I still think that we could do it.
