They live in rural WV, where there are so many children in foster care due to the drug epidemic that the Rodriguez family is not of concern. Honestly, unless you e lived there long-term, it is hard to grasp the level of social dysfunction in those communities. We are in the third, fourth, and in some families fifth generation of drug abuse, poverty so ingrained they see no way out, epidemic levels of hoarding that is symptomatic of poverty and depression, and infrastructure so bad that schools that flooded three years ago were never repaired or replaced.
When you live in an area known for having the highest overdose rate in the country, a family like this can easily pass for wholesome and healthy. They may be underweight and dress strangely and wear too much makeup, but they are clean, not being injured or left alone while their parents get high, and they aren't at risk from drug paraphanlia being left around the home. CPS has much bigger problems.
