I believe that stereotypes have truth in much part of their arguments. But stereotypes are used by people that doesn´t know much about an specific topic. Long time ago one friend of my mother that lives in the United States believe that mexicans walk on dirt roads, that we all carry a sombrero and that we walk without shoes. Unfortunately in some parts of our country there are people that live in this conditions. So thats why people believe that all mexicans used to live as they hear the stereotype.
