I'm not understanding what you are trying to say in your comment? That you can't imagine "tomrod" or other hackernews commentariat have ever gone hungry for an extended period? That you can't imagine a modern community facing food insecurity, drought, war, or other maladies?

Communities built themselves around food production and child rearing 2000-8000 years ago as they nominally do today. I think you may be overstating the disparity in experiencing the negatives (drought, disaster, and war) and ignoring that these conditions also happen today and sometimes also don't get resolved -- people die, starve, drink poisoned water, and so forth.
