The rabbit hole goes deeper.

If the movie describes reality then it does it pretty well and then apparently reality can be described as a joke.

If the movie satires reality and we cannot discern the satire from reality then reality was already a joke to begin with, we just didn't know.

The question is not how did we get here or how did this happen? But how do we get out of here? :)

This is not the first time that what was thought of as satire was actually an astute observation. This happened a lot under communism. A lot of jokes were just plain facts.
