However, since this post is about US GDP I'm now curious, what do you think where this money is going and contributing to GDP?

This cycle has been repeating for me for a long time, I wonder if I'll find a good balance eventually. My current approach is to try and read more technical stuff digital while keeping novels, the humanities, history as paperback, we'll see.

We should maybe just reconsider in general what kind of thing is economically viable

I don't know about how this stuff works, but as a matter of fact there's management bonuses for new development for DB execs, whereas nothing is gained from plain bleak maintenance. So guess why many major train stations in Germany have been undergoing major, multi-billion relocations and redesigns (often with worse throughput metrics).

That seems pretty long - am I misunderstanding something? By my understanding this means the time from enqueue to job processing, maybe someone can enlighten me.
