>and also remember Berlin's system is essentially new and was rebuilt after reunification so you are looking at a modern system.

After the reunification, they only had to reconnect the lines that were separated by the wall. Only a few places needed some extensive work. You probably meant WW2 where most lines were destroyed. Note that Berlin was also one of the first cities in the world to have a metro system.

>No one is keeping you from remaining in Germany, are they? I can guarantee you they will approve your work permit and you can become a resident and eventual citizen.

The horror!

No, they didn't simply have to connect some disconnected lines. Not only did the eastern infrastructure, have to largely be rebuilt from the ground up, but even the western part was outdated and old and reunification meant that billions were spent on upgrading infrastructure.

Upgrading and maintaining a transport infrastructure is necessary for big cities regardless of the wall circumstances. You don't think London, Paris and other big metropolitan cities in Europe spend billions on upgrading and maintaining their public transport infrastructure? I don't see Berlin having a completely automated metro like the DLR in London, or NFC cards like pretty much any other metro in Europe.
