According to the conflict perspective, all aspects of a society arise from the fact that the dominant class needs to keep its power over the other classes. The media is, in this view, a part of this process of maintaining power. The media is used to project the dominant ideology and to get the people to buy into that ideology.
Conflict theorists would say that the American media, for example, does not question the fundamental bases of our society. The media might report on problems suffered by the poor, but it does not question the idea of capitalism. The media continues to put out content that assumes that capitalism is a good system and that all people have the chance to get ahead in our society. This suits the dominant class (conflict theorists say) because it helps them to keep the subordinate classes happy. It keeps them convinced that they could get ahead if they would only work hard enough. This prevents them from being unhappy enough with the system to rebel and destroy it.
