In the end privatizing means maximizing for profits and not other quality factors though. It would be great if that would lead to increased value and quality of service, but that's not the reality in our current form of capitalism. Here, it leads to saving costs whereever possible, which finally implies loss of quality.

When it comes to infrastructure like train networks, telecommunication lines or postal services and critical services like hospitals, privatizing is the worst you can do from my point of view. Living in Germany, I see plenty of such examples. Our train service got incredibly worse since it was privatized, hospitals have severe issues on multiple fronts, and let's not forget how we are extremely sucking with the modernization and upkeep of our telecommunication infrastructure.
