Wild Ones

I have recently realized that so many novels, especially young adult, have children without parents. How are all of these orphans running around without supervision. Even with television shows, kids have lost their parents and just run around free. Does anybody ever realize that these children are minors and should not be out alone? Where have all the parents gone? I feel like this is becoming a key component of all sci-fi,fantasy and dystopia novels. Lets kill all of the parents off and let the children run around getting themselves into trouble. And then they make these huge life decisions and take on the world…they are like 16…what do they know about anything. Someone needs to wrangle all these children in and tell them to stop causing problems.
