Alienation for Marcuse has a strong claim to being dialectical. Yes, he agrees with Marx that it causes unhealthy estrangement from ourselves, others, and the world. But he argues this estrangement creates in the artist a healthy separation from the world as it is that allows them to imagine, and inspire the world as it could be — an aesthetic way out of capitalist realism.

As far as fighting causing alienation in relationships... The fight isn't against people, but for the right to live in a better world, one that doesn't alienate us from our own labor and production, from people we treat as things, from our natural and built environments. Attempting to find "resonances" within this system in the interest of preserving our survival and sanity is understandable, but it amounts to an adaptation to alienation, not an overcoming of it. I think about the opposite of alienation as connection. A collective struggle to this end seems a potent antidote.

To perhaps find resonance with you: this struggle should be concrete and communal rather than abstract and impersonal — enacting connection within personal relationships as it fights for a more connected world.
