Disclaimer, I only read both of these diagonally.

The first, while focusing on a capitalism lens, isn't a unique problem. It's an alienation effect possible in any community. Reducing barriers to migration and employment can reduce it on a macro scale. On the micro scale it's just the human condition.

The second, while certainly packaged toward a specific audience, does not differ from conventional thinking or guidance on mental health.

Would anarchists even cease to exist in solarpunk? It should just be a change of focus from a capitalist status quo to a solarpunk status quo. This distention is healthy for any society.
