People have no idea how food is grown or how it gets distributed. And the first domino to fall will be the inner-city hellholes because delivery drivers will NOT deliver food once the bottom falls out.
Farmers here grow beef cattle. If they sell direct to consumer, the prices are near double store prices. Some people do garden so that’s good. I think a lot of people would starve before they pick up a shovel these days. There are farmers markets here and prices are decent but everyone grows the same handful of items. Maters, green beans, cucumbers mainly.
