A good start would be getting people to learn how to socialize properly. Either by creating programs for young people to meet up and do stuff together or by restructuring the education system to place a bigger emphasis on co-ed socialization. There's an uncomfortably large amount of people who do not know how to socialize. By that I mean they're really clueless. They don't know how to carry a conversation or how to properly react to situations or understand basic social etiquette or ask somebody out that they find attractive or anything really. I've seen a lot of these people when I was in university, and they are as awkward as they sound. It's not just anecdotal either, the loneliness pandemic is backed up by data. There's huge chunk of people with few or no friends and this demographic is growing. If we can find ways as a society to encourge young people to socialize again, the benefits will be huge. Their mental health would improve, their confidence would get a boost, their social circles will expand, and from their new social circles they have greater opportunities to meet a partner.
