Good question. Probably see inflation skyrocket over the coming days/weeks across all consumables. Mass job loses, business close over the coming weeks and months. Shortages across the board, delayed deliveries or none at all. Restrictions put in place, likely to curtail movement. Crime skyrocketing. Gang violence. Lack of police. Martial law at some point. Bank holidays or flat out service denial so no money for us plebs. They would usher in a new currency which will take time for a transition. Families will fall apart, suicides, mass abuse of alcohol, drugs, domestic violence. Power, internet loss or interruptions. Government trying to increase it's power and control.
