The assumption that American prosperity in relation to the rest of the world is based in high values and moral superiority is false. The U.S. is not a city on a hill. It is a castle supported by arms sales and exploitation of poor populations in collusion with its allies.
The great lie of politicians like Hilary Clinton and George W. Bush is the representation of the U.S. government as a civilizing force in the world. If "civilizing" means selling weapons to and exploiting the resources, natural and human, of other nations, then the U.S. is certainly a civilizing force in the same way that propagating fundamentalist Islam makes Saudi Arabia and Iran civilizing states.
