You can’t stock for families that don’t.
I would bet(and win the bet) that 95 percent of families around you would be lucky to make it a week if the trucks stopped.
Heck, three days after the milk disappeared from store shelves, all hell would break lose.
People tend to get a little excitable if they watch their children starve.
I am constatnly amazed at how people don’t prepare for anything at all. I work at a store in a northern climate and every time there is snow, the hordes come in DURING the blizzard for milk, toilet paper and other essentials. They keep nothing on hand and always expect stores to be open and fully stocked. I pride myself on the fact that my family could live for at least 1 month (and am constantly working up toward more) without stepping foot in a store if we had to.
That's what scares me. I live in Los Angeles, and I can just imagine. I have some emergency supplies, but I spend a lot of time trying to figure out where I'd hide them from the rampaging hordes, because it would be Night of the Living Dead here in a matter of days. Even a gun would be of little use if seven or eight desperate people were coming in the windows on all sides.
