I imagine Most people will either learn to COOK FROM SCRATCH,
Stop buying fancy organic
Stop buying deli-premade foods
Stop buying partially premade "kit" foods
Stop fast food eating out ,
Be happy to even be able to afford carrots, rice. cabbage, onions, potatoes, corn meal, flour. Salt, dry beans, lard, and ANY kind of protein, even offal (heart, liver. Tripe, tongue. Tail, kidneys) or carp or other trash fish, and rarely, a couple-3 times a month a chicken.
Our life will quickly change from LIVE TO EAT to. Eat (most anything edible) to LIVE!
