Society is being radically transformed.
Is anyone surprised at the results?
You are right. We are now at the Lord of the Flies stage of our society.
It started in the ghetto, so most people who did not live in the ghetto just wrote it off. But right now 40% of American children are born to single mothers, and only a dwindling MINORITY of American kids are raised to adulthood in homes with both biological parents. Bottom line: the kids raise themselves, just as these charming characters did. When they need "help" (like to dispose of the ashes of their victims), they can always call on mama's latest boyfriend (AKA "stepdad").
