A saying most black Americans will be familiar with is, "It takes a village to raise a child." It resembles proverbs common to cultures across Africa; one could say that it's cultural knowledge embedded deeply within the African diaspora. American black culture is often derided as being inadequate, particularly in efforts to raise well-adjusted and pro-social children, but what's rarely mentioned by these commenters is how frequent and widespread are the historical and contemporary destruction and dissolution of black communities in America. In the too-common case of single mothers rearing children alone (the absence of the father often itself a product of poor social support), the difference seems to be in the presence or absence of older siblings, grandparents, aunts, uncles, and supportive teachers, especially when the mother is forced to work multiple jobs in order to cover ever-increasing expenses. (It should also be noted that when the father is present, married or not, he tends to spend more time with his children than fathers of other ethnicities.)

I bring this up in order to maybe open some minds as to why we see racial disparities of certain types - and also because, as mentioned by another commenter, the increasing atomization of families and communities of other ethnic groups threatens to replicate the aforementioned dysfunction. Common and widespread understanding of the dynamic could head-off tragedy; they hit us with crack before they hit y'all with opioids, after all.
