This has happened in two generations. The school is no longer a community center. Parents don't involve themselves in helping the school, only in complaining. PTSA meetings often have more teachers than parents, unless there is free food. Education is no longer important.
School is viewed as day-care.
In the current situation, public and media concerns center on child-care, not education. Baby-sitting, instead of educating. The concerns are not that children are losing education, but that parents are losing work time. Parents of special-needs children are lamenting how they must take leave from work to care for their child. Of course, that is a major concern.
