I'm obviously exaggerating, but not THAT much.
You can't just paint over that with an analogy. Maybe I just treat my kids different, but there's literally nothing about work that I care about even remote as much as my childrens' well-being. I'd burn my inner company to the ground if it meant they get a chance at a decent life. I believe it's a biological imperative to remain willing to self-sacrifice to any necessary extent for the betterment of the offspring.
I'm not really sure what your objection to this analogy is.... Choosing to work more so you can send your kids to an elite private school is one action that somebody can take. Choosing to work less so that you can be more involved in your children's lives is another. All the analogy is asking is that you be intentional about how you are managing yourself and your household.
