Common Weal, often written as one word, commonweal, but which I separate to highlight both elements. The notions are not frequently encountered and may seem old-fashioned. They are to me the essence of community.
The common element is clear.
Weal has connotations of both health and wealth, in the sense of overall welfare, sharing roots with will, "to wish, desire; be willing; be used to".

Common weal is the sense of a shared interest, striving, and achievement of health, wealth, and prosperity within a society, that very real thing Margaret Thatcher so famously and falsely claimed did not exist. The only way a society can not exist is if it is not defined by a common weal.
The alternatives are a mob, separate factions, host-parasite, or predator-prey relationships
