There are, of course, multiple causes for loneliness. We can't fix them all with one clear action. Here are the main five, in my view:

First, social media. It's too easy to temporarily forget about your loneliness by staying home and doomscrolling or watching TV.

Second, increased mobility. People move around the whole continent now for work, removing them from their closest and oldest social connections.

Third, God is dead. Churches as community centers are dying out. Young people don't trust them anymore, because they don't believe in God, and because churches had many scandals. Secular community centers are very rare and struggle with funding.

Fourth, work is more stressful now. There used to be more time to socialize, but in our quest for productivity, work became denser with fewer idle times.

Fifth, fewer people want to have kids. Much has been written about this.

Now what can we do at societal scale? First of all, study the phenomenon more closely. Who is lonely? Who isn't? Which interventions work? Which cultural factors are important? At your local scale, you can just call or meet a friend.

The we here is not most people.

The quest for higher productivity is not something people really care about.
