Maybe it would make more sense to stop talking from the lens, from the perspective, of "some people in society are privileged because of their parents' good childrearing and organizational choices"...

.... and start talking about this instead from the narrative of "some people in society are being damaged because their parents are making the choice to be badly organized and to use incompetent childrearing approaches".

See, thing is, in medicine the goal is to correctly identify the DISEASE and then to seek treatment for the DISEASE. Which is to say that it would be kind of useless if medical doctors spent all day long talking about nothing but how well the body works when it is free of disease (and perhaps implying that those out there who have diseases, they ought to be envious and resentful and bitter toward those in good health).

I think there is a profound lesson in that medical vignette for all the social justice warriors out there...
