> The median adult is spending 5+ hours on their phone a day. This is what is exhausting people.

When I am tired from work, I spend more time on phone after. And less time doing other more engaging activities. When I had easy workday, I am more likely to do something else.

> Poorer people are making more time for friends and family.

This is what I found: "the social interactions of those from lower-income households tend to revolve around family members and neighbors" and "richer people spend more with their self-selected friends".

This would confirm exactly what OP wrote - people who do socialize do it with people nearby.

> I can see what you're trying to do - reframe this problem as another outgrowth of class struggle.

They are referring to what they see as they do their community organizing. You dismiss it all, because none of that should theoretically matter.
