It's not a purely cultural problem but mostly a political problem.

Germany sold out (a lot of it under the table and really fast without proper oversight) all of the good working stuff in the 90s to investors and the state kept all the bad stuff so there's no money or will to invest. All of your examples were state owned and operating nicely in the 80s. And then the CDU basically froze all progress for years under the umbrella of saving costs (instead of taxing the rich and companies and opening a lot of loopholes to transfer assets out of the country)

So all of the infrastructure in all aspects is on its last legs and somehow now you can't build stuff anymore anywhere apparently because everything takes forever in the western world especially in Germany where maddening Bureaucracy is apparently a good thing.
