its a worldwide assamption that native speakers are better than non native speakers. especially it is irritating since i have graduated the same faculty in english lit as native speakers with the same grades and sometimes even better. language is something u have to feel... anyway, for me its the same story , they are veryyyyy impressed by my accent and level and hire an american instead coz im not blond and overweight , which sorta is the convention of how an american teacher should look like
