Yes, but lack of personal accountability and bad parents are both products of the root issues that @
RevolverRob is talking about. With the root issues present, we'll continue with the trend of bad kids becoming bad parents.
Even if we were to fix the root issues overnight, it would still take several generations for the family issues to improve.
This isn't an excuse to bad behavior in society....it's simply an acknowledgement to the "why". It's no secret that kids who grow up in awful conditions but have some sort of positive support network which sets the right conditions that Rob is referring to (such as an afterschool program, JROTC, boy scouts, church, whatever) tend to come out ahead compared to kids that don't have that support network. That support network teaches them personal accountability, and they usually go on to become productive citizens and good parents.
