We don’t even have to zoom in on Europe. In the US, it’s quite common for folks to expect public services (like public transit or even the USPS) to be profitable. Which means these services don’t get the investment they really need.
Municipal services are meant to serve as many citizens as possible, not to extract as much profit as possible, because it’s an overall benefit to everyone.
Just looking at money is incredibly short sighted and naïve
The entire point of a public service is that benefits accrue to people other than the direct consumers of the service.
