This is a systemic issue with the Western way of thinking. The West always consider itself to be the most evolved culture in history. First, by way of Christianity, later, by way of markets, democracy, and science. This way of thinking is self-deceiving because they cannot understand that other cultures can offer something equal or better. So, when faced with the advance of other cultures they necessarily have to dismiss them as inferior.
This isn't really unique to any particular culture. China spent a good couple millenia referring to anyone outside its borders as 'barbarians.'
Well, they clearly don't have that issue anymore. Maybe that's why they're now where they are.
