In the US, the rails are private and the government owns the passenger service. In Europe, the government owns the rails and the passenger service is private.
People try to frame these issues as "socialist/capitalist" or some nonsense all of the time. But the reality is that neither system is more or less capitalist than the other. It's just one is better structured than the other.
However, having lived in a town in the US that has had a public ISP for decades, it was abhorrent. Municipalities only care about cost cutting - so there was no investment in wiring infrastructure or customer service. So I think there is an argument to be made that we may take for granted a bit the difference between rails/roads and fiber optics.
