One Dunedin Study https://en.wikipedia.org/wiki/Dunedin_Multidisciplinary_Heal... result shows that a "disadvantaged" childhood combined with a certain set of genes leads strongly to anti-social adults (well, men). The same genes with a good childhood tends to result in entrepreneurs.

This result really hit home for me, because I was removed from a badly dysfunctional mother when I was ten, and now run my own startup.

It seems to me that as a society, we should be a lot more focused on raising our young - failing them incurs the direct cost of their crimes and a lost opportunity cost of the businesses they might have developed.
