Isn't that basically what happened to the USSR? (Yes not technically "first world" but highly industrial and bureaucratic)

Someone already assigned "Fourth World" to stateless nations, so it's probably fifth world by now.

The developed world does have decaying infrastructure but moving it between the private and state sector has caused problems. As has lockdown and other international policies. Our local government's main interest seems to be in shutting streets off and designing bad cycle infrastructure that is little use to cyclists (I am one by the way). It is letting our streets fall to pieces and spending lots of money erecting physical blocks.

This is just silly. The German train system has problems. Does that mean total civilizational collapse? No, it doesn't.

I am sorry but this is not Rao's but Umair Haque's and he considers the UK and the US Fourth World.

There's no indication of any failures of the industrial layer in this story. The train was working, it didn't crash into anything, everyone was safe.
