Absolutely reliably the best way to increase your chance of survival in a situation like this is to have good relations with your neighbours in a good community with high trust. A large number of people working together will be much more likely to find solutions than a few isolated individuals. The isolated individuals may have disproportionately large survival resources, but probably not for long. If you are in the caring-is-sharing group you will have a much better chance than being in the me-me-bang-oh-shit group. But there are a lot of people who fear community solidarity because it might lead to people asking questions about private jets and beach condos.
