I'm not quite sure I follow your question. Are you asking how do I know that someone who loses their job needed their job to afford groceries? If so, I guess I felt it was a safe assumption that the people working at grocery stores are not financially independent.

No not my question. Sorry if it was unclear. I'm trying to understand how you're thinking about this. The question is "are there numbers x and y for which it's good that x number of people who would otherwise go hungry eat food even though it costs y number of people their job"
