You linked me to a website for a US organization that apparently encourages the extremely wealthy to create more tax shelters for themselves, and followed that up by pointing out that the US accounts for 28% of the world's billionaires while making up 4% of its population.

I'm not sure what point you were trying to make. I don't think we have a monopoly on greedy businesspeople or politicians either, but I do think that as the epicenter of global capitalism, we dominate the market. You can't hope to solve problems if you won't allow yourself to accurately define them.
