What do you mean material conditions? The class system at large? Sure, ultimately, but it's alienation that would be the more specific Marxist term, and maybe some post-modernism would apply here as well to explain phenomenal like how much consumerism is involved in relationships now eg. a nice date means eating at an expensive restaurant

Removing some aspects of alienation should help, definitely. I used to live in a large cooperative house where I felt the most connected to others in the same state as me. As opposed to the competition and awkwardness of school and work otherwise. I also feel more connected when with my extended family back in the old country, where multi-generational housing is more common, and old traditions like farmers' markets still exist.
