There are many questions that should be asked and answered. For example:
Why does it suck so much to be forced to miss having a childhood in order to grow up fast?
And related to it:
Why are people who grow up in poor, crime-ridden neighborhoods different than those who have coddled childhoods? Why do those living in violent, war-torn communities struggle so much? Why is it so hard for those without freedom, opportunity, and resources to live up to their full potential?
Why do desperate people act desperately? Why do isolated, stressed people become addicts? Why do unhealthy conditions create unhealthy people? Why does poisoning children lead to dysfunction and violence?
Many, many questions. But the most important question of all: Why do the privileged and comfortable so rarely ask these questions?

Young Mice, Like Children, Can Grow Up Too Fast
by Alison Gopnik, WSJ
In the new experiment, published in 2015 in the same journal, the researchers looked at how the young mice reacted to early stress. Some of the mice were separated from their mothers for 60 or 180 minutes a day, although the youngsters were kept warm and fed just like the other mice. Mice normally get all their care from their mother, so even this brief separation is very stressful.
The stressed mice actually developed more quickly than the secure mice. As adolescents they looked more like adults: They were less exploratory and flexible, and not as good at reversal learning. It seemed that they grew up too fast. And they were distinctive in another way. They were more likely to drink large quantities of ethanol—thus, more vulnerable to the mouse equivalent of alcoholism.
These results fit with an emerging evolutionary approach to early stress. Childhood is a kind of luxury, for mice as well as men, a protected period in which animals can learn, experiment and explore, while caregivers look after their immediate needs.
Early stress may act as a signal to animals that this special period is not a luxury that they can afford—they are in a world where they can’t rely on care. Animals may then adopt a “live fast, die young” strategy, racing to achieve enough adult competence to survive and reproduce, even at the cost of less flexibility, fewer opportunities for learning and more vulnerability to alcohol.
This may be as true for human children as it is for mouse pups. Early life stress is associated with earlier puberty, and a 2013 study by Nim Tottenham and colleagues in the Proceedings of the National Academy of Sciences found that children who spent their early years in orphanages prematurely developed adultlike circuitry in the parts of the brain that govern fear and anxiety.
