Social group and issue

The only social groups/issues really being discussed here are mental disorders and how the socio-economic status of America has given middle-class American's too much safety. The mental disorder factor, however, will not really play such a large factor into the film, it's much rather an additive detail. The issue of socioeconomic status is huge. The film takes place in a small sized suburban neighborhood. Most people that live here are well off for themselves. But that doesn't mean you should keep your guard down. Many middle-class Americans move to suburbs for safety and leave their doors open as they fear nothing could ever go wrong. However, this is not true. No matter where you live, you should always keep yourself safe, and be aware of your surroundings. Just because you live in a good looking neighborhood does not mean you are susceptible to crime, murderers, and absolute sociopaths. Many Americans refuse to believe this, as they believe danger can only come from the inner city.
