What they need to remember is what the Mexicans learnedd a long time ago: you can feed a lot of people on beans, rice, and cornmeal. Then the money you save, you can buy fruit and vegetables, or you can grow these in the garden. Trouble is, many folk have forgotten how to do what their grandparents could do.
I may need to get in on this if there are jobs for people like me in their 40’s out there.
