This occurs in poverty, especially generational poverty. People, white supremacist-minded people, racist people, ethno-nationalist types like to pin this on certain communities, notably in this country black communities.
People need to understand their racism. It's not always white hoods and cross burnings. Sometimes it's as "benign" as tending to associate certain issues with specific groups and subgroups by skin color or national origin or whatever. The fact is, in my experience living in and working with inner city, mostly black, communities, "breakdown of family" is a misnomer. "Family" takes on all kinds of amazing shapes in stressed communities. But that's a whole other conversation. It would be better described as "breakdown of society" in that rather than truly work to understand how capitalism creates both wealth and poverty, and, in the case of this country, generational and often discriminative poverty, too many of us choose to associate certain issues as a "those people" problem.
Nope, we're all involved in the problem, especially when we choose to remain mostly ignorant of the full breadth and scope of it.
