It actually is arguable that the US operates as a monopoly. The main reason for poverty and depression in 3rd world countries that are rich in natural resources and fully capable of supporting themselves is that they develop a reliance on American companies to provide them with luxury goods that they don't really need, and they trade the minerals that their country has been blessed with in order for the rich of the country to be able to afford these luxuries. As a result, prices of everything else are driven up until even necessities like food and water become unaffordable to the average person. By cornering these markets and being virtually the only producers of these luxury items, in a way America has acted like a monopoly around the world, where countries are forced to do business with us because no one else makes, lets say, Coca-Cola for example.
That kid is an idiot though so he would never be able to figure that out.
