We see reporting like this every day on television and radio and in newspapers. While the majority of young people contribute to our society, that's not the reflection we see in the media. The job of the news media is to inform people of what's new and interesting. In order to stay in business, media outlets depend on their audiences.
Large audiences attract the advertising dollars which keep the newspaper or the station running.
So ultimately, media outlets cater to their audiences. The pressure is on media outlets to produce a large amount of news for the same or next day. To meet the deadlines, most journalists are forced to cover stories quickly, and often, superficially. Reporters have to produce work their audience will like. Their job is to grab attention, through a vivid written description or an arresting image.
