But don't you know, 60 years later, after WW2, the labor market worked out. After a few minor details happened in between. So things turned out fine for the buggy drivers and you are freaking out just because you are the new buggy driver (things did not in fact work out for buggy drivers, but that's just a small detail glossed over because things worked out for people after WW2, we have no idea how buggy driver's lives turned out in our example of everything working out for buggy drivers).
Things will be fine (it might take another 60 years and a few minor details, but it will all magically work out, like it did then. Not for the buggy drivers though. They were fucked, broken people living on skid row grew so huge it was a popular trope in children's cartoons).
Factory workers didn't worry about cars, but buggy drivers did. Office workers didn't worry about factory automation, but factory workers did.
