Critical are the communities and communal activities. Those have disappeared. We need to live in environments where people eat in communal environments not centered around nuclear families. That’s the critical piece that is missing and making everyone feel empty.
Music and dance is but an aspect of this.
Generally humanity evolved to live in tribes and that is where we are most content. In modern times the closest where I’ve seen this is living in dorms or places with shared kitchens and communal eating areas. This promotes the type of communities that make humans happiest.
There was a wave of business plans and startups that tried to tackle this problem by building apartment communities that are more “social”. One that exists nowadays is https://www.flow.life/en/. But these businesses get it all wrong because they lack the communal kitchen and eating areas. The environment needs to have a forcing function to make people form communities not have it as some optional social event. The former makes people much much much closer and the bonds much stronger. Anyone who’s lived in such an environment can attest to this.
