That can be achieved in different ways. The health of communities does not need to rely on earning money, there are plenty of other ways to build a vibrant society that still values the contribution of individuals.

Without having to toil for survival, people would be much more open to participating in bettering their communities outside just doing whatever can net them the most profit. Easily expect volunteering and charity to dramatically rise under a UBI.
