Has anyone ever read "The Spirit Catches You and You Fall Down? It's a heart-wrenching story of a poor kid with serious epileptic problems with complications, coming from a culture that both didn't understand the modern medicine, and working with doctors at a time (1980s) when the whole spiritual/holistic thing wasn't yet a thing. Everyone involved wanted the best for the kid but collectively they weren't capable of providing it. CPS got involved, courts, translators, spiritual leaders, doctors, nurses, etc etc. Ultimately it didn't prove possible for this child in this situation to be both with her family and receiving proper medical treatment, and sadly she did eventually die.
That's an extreme case with some great examples of how things can go crosswise but to some extent I can understand even in lesser cases where the line can be fuzzy. It's a bit of a leap to say there's a cultural gap but given the names of the parents this seems feasible. The Russian community in Sac and Seattle can be confrontational, distrustful and abrasive when interacting with Americans, and unwilling to work within proper channels. It wouldn't surprise me that, acting entirely within the best interests of their child, they tipped off some red flags that made it seem like they did not have intent to provide her proper medical treatment and care.
