People still pay their taxes generally. People still send their kids to school. People still believe in the system. People still do their groceries. People still go and work their job.
But there’s no life to it. The skeleton of the civilization is still around but there’s no organs to it. Culture, civilized life, gatherings, parties, everything is gone by now.
It can be compared to a chicken that got its head chopped off but still running around, creating the illusion that the chicken is still alive.
