Preppers forget that society preps, too, just not necessarily at the individual level. We have warehouses full of extra stock etc, and carefully-managed supply chains, and emergency services. This is all prepping.
I think preppers should pour their energy in to helping society prepare, and not just turn their back on the very reason they exist.
p.s. I don't consider taking sensible precautions like having a well-stocked medicine cabinet, fuel in the car, and some food in the freezer "prepping".
