Nick yes it has fallen to be our responsibility the day we said a 14yr old kid could decide to have an abortion or keep her baby.  When we decided that kids could have kids & take care of them.  

When as a society we determined that minors could actually raise minors & the govt would pay for it, yes we did become responsible.  Each &  every one of us became responsible for everyone else's kids. 

Used to be a teen got pregnant & that kid was put up for adoption, (kids had no option) it was better than saying yeah 12-16yr old kids could actually be responsible enough to raise a child.  Now we literally have an entire segment of society that is a child raised by a child.  

So those of us who are capable have to step up to the plate because otherwise the actions of some sloppy folks will impact everyone's lives.  You can either mentor a kid or keep your head in the sand & watch while a kid tries to steal your car. You do have the choice to be helpful rather than justa keyboard warrior.
