I'd assume almost all Star Trek civilizations have their own "post-scarcity utopia", but it could be incomplete and/or not quite an utopia because of racism (e.g. Romulans), slavery, problematic culture (e.g. Klingon expected lifespan), villains, catastrophes and other Enterprise-level trouble.

Good guys like the Vulcans seem to have only personal and psychological problems, not material ones.
