Victim blaming a failure of society as "cultural" is disgusting. How do you expect people to solve structural issues themselves? Even more without any kind of support if they take a wrong path in their lives?
It sounds like there is no empathy in your speech, as in if someone took a wrong turn then they deserve to suffer for not having lived a perfect life with perfect choices.
A decent society would look at these problems and fix them in multiple levels: better education and support for teens to not get pregnant, opportunities for those with kids so young to be able to change their lives so they don't perpetuate a cycle of misery.
This is a failure of American society, its values and your comment just make it clear what is wrong in the public mind and discourse about these issues, these people are also people, unfortunately growing up in much worse conditions than you probably have and this, in the US, will completely impact the rest of their lives.
So please, think about the bigger picture here, use some empathy and stop perpetuating this idiotic "individual responsibility" discourse.
