How come no one ever dies in kids cartoons?

I believe that Happy-go-lucky is the point of cartoons. It is an escape from the 'real world' that is why we enjoy them so much. There IS so much death, destruction and general depression around us that there has to be someplace where there is none of that. I think that cartoons are meant to teach children about the good things in life. Why would anyone want their children to grow up cynical because they have seen death and darkness everywhere? Children need time to be children, to have the happy-go-lucky dreams. I'm not saying that they should be sheltered from everything, and told pretty little white lies, but there is a time and place for that. That place is NOT in entertainment meant to give hope, hilarity, and just a little bit of nauseousness!
