Statistically; if you want to increase the odds that a child will drop out of school, go to jail for violent crimes, among a laundry list of serious correlations, ensure that the child has a distant / absent / negligent father and an overbearing single mother.  The other issue with this all-too-common scenario is that when boys have no personal male role models, they get them from media - and with media you either get the soy boy cuck or the shoot-em-up macho psychopath.   That leaves lots of boys believing that violence is a proper way to exercise their "masculinity" in defiance of the overbearing single mother who normally has a very skewed and weaponized form of nurturing.
