We are talking about corruption so from your post I gather that Americans are also not ethical?
If there is a perfect nation among the 190+ around the world, I've yet to see it. However, an honest study of the subject would not even put us in the top 50th percentile.
I'm especially not going to listen to criticism from an individual who made a very good living in the American market and supports a nation where you cannot even do a Google search on any subject.
