I don't have a child, which frees up a heck of a lot more time for me to find other ways to focus on making money.. whether that's working longer hours to earn better performance reviews/bonuses... researching investment opportunities... or creating my side business... all of which I have done

(oh, and before 57 screams about my privilege, I grew up lower class)
I think though what is causing the two groups to diverge is the increasing premium to education. And looking at well-educated single parents would show this. We are talking about somewhat different things. You point has to do with the gap between various groups. My point has to do with why the gap is growing.
