We have never faced a crises of really bare shelves throughout the grocery store. In the past, if the Hostess Twinkies were gone then then there were still Little Debbies. If every can of beans, every bag of rice, every tin of sardines, and every calorie disappears from the stores then how will our spoiled population behave? They do not have experience at foraging for dandelion roots, cattails, and poke sallet. If we get to the point of truly bare shelves then the violence will be incessant.
I’ve noticed barer shelves even today.
Now, I grant you, the shelves may be barer because of a lack of available employees to stock, but that, too, is a supply-chain disruption.
Back when Nixon put on some price controls, our local store had lots of bare shelves. Reminded me of pictures we had seen of Russian stores.
It also taught a valuable lesson - put price controls on everything you do not want to be available-shortages are easy peasy this way, and of course, you get to claim that you are standing up for the people.
