I asked the natural question - why. He replied that gringos walk around as though they're better than anyone else. They are so proud and egotistical. They come here and look at everything we have and just think the US is better. As the conversation developed, deeply felt prejudices and cultural insecurities came forth.
Gringos think they are the most important people in the world.
They don't know anything about anyone but themselves. They don't need to know about anyone else. They don't need anything from anyone - they have it all. You can't really learn about others if you can't speak their language. There is so much history and culture to be learned in another language.
