MTV: Altering the Shows?

Does MTV alter the conflicts between people in their shows? No one knows except for the channels who run the shows and the people in the shows, but I'm pretty sure they do. In the shows involving pregnant teens and their families, the shows often focus on the teens screaming at and arguing with their parents. It's hard to imagine parents and teens yelling as much as they appear to be doing in the shows, making it seem like MTV is blowing the situation out of proportion. They should realize that it's wrong to be interfering with their clients in order to produce better television.
