Nobody wants to live on rice and beans for long, but in an emergency Walmart sells a 20 pound bag of rice for $11.14 and a 20 pound bag of Pinto beans for $14.94.
Walmart peanut butter,2-4 pound jars $12.94 and 4-30 ounce jars of jelly for $9.84 and 6 loaves of bread for $8.52, 4-42 ounce boxes of oatmeal for $16.72, 8 pounds of sugar for $6.14.
For $80.14 one has a base survival food box that kids or any adult will choke down for a few weeks, consisting of 2-4 pound jars of peanut butter, 4-30 ounce jars of jelly, 6 loaves of bread, 20 pounds of rice, and 20 pounds of pinto beans, 11 pounds of oatmeal and 8 pounds of sugar.
Throw in what one has at home and a few dollars to flesh out that survival diet, and a woman and a couple of kids, or a couple, can hang on while this sorts itself out.
Thinking people can do much better than this basic Walmart example, but this list would work for even simple minded households.
Soldiers who put their lives on the line should not be forced to ration as though they were on a battlefield — by the very politicians sending them off into war in the first place, who I assure you, are NOT rationing themselves. And nor are their families.
