It used to be easier in smaller cities and villages where you were forced to know a lot of people. One of the side effects of being able to live more private lives in the modern age is this lack. In the same way that churches do provide communities (but I still think religion causes far more harm than good).
This is why social safety nets are important - because the baseline should not be "I know a guy".
Social safety nets for trucks? Maybe not specifically. But you can easily rent a truck in most places these days - $20 for a couple of hours.
But then again, if you think about isolation… that's where some of the ideas about witches came from in days past. Imagine a woman, losing her husband, living alone, struggling to survive. Society is more "spiritual" and so susceptible to believing some of those old women might be witches. It certainly happened in some instances.
Ideally, I wish we had a society and culture in the US of knowing our neighbors again. Not too much. I don't want to know of their politics and religion and all the other things I probably disaagree with, but I'd love to be able to give them a cup of sugar if they ran out, or help move a sofa, or all those little things we used to do a bit more for each other.
