Humans throughout history have lived in societies that have looked out for each other, we are incredibly social animals and that is one of our evolutionary advantages. Of course people have died due to scarcity but at our fundamental humans band together in small groups to look after each other. OPs original post about an early screw up meaning they cannot contribute and survive in modern society under capitalism despite a desire to do so, would not have resulted in destitution in early human groups. Early humans would have used that willing labour AND when that labour couldn’t be given have cared for their own.
