I think you're right as shown by rich parents being more likely to have rich kids, violent parents have violent kids, poor parents, poor kids, etc. The trouble is, those violent people become parents too so they perpetuate the same problems. Without training, what's there to help whole cultures filled with poor parenting being passed on through generations?

"I want kids, but I wouldn't be a good parent so I won't have any" said nobody ever.
