One of the larger malls in my area had managed to remain successful and busy for many years after others had begun to decline. The cry was raised that public transit needed to be made available to that mall because of store closures at other malls, and it was. Now, it’s declining too. The gang-like territorial behavior inside the mall, combined with fear of robbery or assault outside the mall, sends shoppers elsewhere, to other retail establishments or online.
Yup, the death of civility is a sure sign of the death of a society.
