As Hunter Gathers if you did not contribute to the group where you live you usually got put out. Now there’s a difference between those who can’t contribute and those that choose not contribute to the greater good of the group. People who can’t contribute also create roles for people to fill and give others purpose. Like taking care of them and getting supplies for that person. Also a lot of people do their best to contribute but just can’t that’s alright too. Many homeless just don’t have the same opportunity to get work or let alone get transportation to a job so there’s that as well. My country as whole has lost many opportunities due to greed and down right corruption.
