Representing the majority of the world

One third of the world population has more than enough food to survive. One third of the world population has just enough food to survive. The rest does not have enough food to survive, that is, they are dying. So, the primary motivation of the majority of the world population is to survive. However, most movies today do not represent the majority of the world population. Movies do not always have to reflect the reality of the world, but it's a bit sad that there are only a handle of movies even attempt to represent the majority of the world. Dirty Pretty Things is one of movies that those who belong to the majority group play the central characters. I suppose that Spanglish is also one of those movies, though the tone of the story is much more cheerful and half of the central characters belong to the minority group. I'd like to see many more movies that represent the majority of the world population.
