Yep, I think it's more that the US and other similar countries have become less community oriented and the social fabric has weakened. As we've become less religious, many people in towns/cities have lost their primary shared social gathering point (Church/Temple/etc), and it doesn't seem like anything has really replaced that yet. Social media has to some extent, but it's a meager gruel compared to gathering in person.

Sometimes I've thought about what could replace this. Maybe some updated version of the Rotary Club/Lions Club/etc?
