There is a complete collapse in what people understand to be 'normal behavior' in some parts of America. It IS dysfunctional, but it replicates itself from generation to generation due in no small part to the layers of handouts the government provides that permit the dysfunctional elements to propagate (and actually grow in numbers!)
Promiscuity is not considered a mental illness today as it was when I took psychology courses in college. (Of course back then homosexuality was still understood to be a mental illness)
