I think the assumption that you will be alone if you don’t have kids is completely false. I have a very cohesive friend group composed of both people with and without kids, and the youngest person in the group is 30 - most of us are in our 40s with a few early 50s. We just make a point of spending time together and fostering these friendships. We have various annual gatherings throughout the year hosted by different people and we get together at least once a week in person and hang out, play games, chat and laugh and just have fun. We like to say that our group is the family we chose.
Friendships don’t just magically exist - you have to be an active participant and it takes real effort, but that’s any relationship. Sometimes you have to go do things with/for friends even if you don’t want to. If you want lasting meaningful friendships, you have to put in the effort.













Public transit absolutely could work in America, but we would need to change how we design our cities as well as how we live. Many Americans live in sprawling suburbs where public transit is just not realistic. In places that are densely populated public transit does exist and functions well. The issue is that we build sprawling cities with massive suburbs filled with single family dwellings each with their own yard and space. We do the same thing with stores by having hugely sprawling shopping areas (most of which is separated by massive parking lots). It’s a chicken and egg problem. You won’t convince people to give up cars until they can realistically walk or use public transit to get where they need to go efficiently, but you also can’t make things efficient and compact while there is a huge demand for car storage. And beyond that, I think culturally most Americans don’t want to live in densely populated areas. Americans culturally put a high value on personal space and that extends to dwellings. Sure there are definitely people who want to live in an urban center, but the “American dream” is a house with a white picket fence and a dog, and until culturally the desire for that changes, America will be a car-centric society as a whole.
