Why should All heroes be different with culture, language or skin color

Heroes' should be different  with culture, language and skin color to be a role model to all kids/adults around the world. If all heroes were the same as Superman with the same skin color, Hair color, & culture all kids wont have a Hero/role model to look up to to be like because they would think you have to be just like every other one (If they all were like superman).
