The falling analogy doesn't really work does it?

I thought the point of it all was to address the absurdity of saying, "So far so good," when how you land, the inevitable outcome, is what's important. It's a futile exercise when you're going to hit the ground anyway.

That can be seen in the film. Vinz's comments and posturing along the way don't matter because he'll ultimately end up dead. This tension between the police and the people will persist. It's not an inspirational quote. It's packed with fatalism.

the point of the joke told by the character (and the narrator's repetition at the end) is that the falling guy/French society are deluding themselves into acting like things aren't as bad as they are. that the falling guy is certain to meet a bad end is the point.

A nice response here.

Apart from the french society falling there is another viewpoint- a more micro one.
It also talks about the youth, the different characters in the movie. Everyone is on a downfall, there is no future. But what matters is how u land.

Hubert could have just survived this landing if he could have left all this.

Same goes for Vincent, he was a person who hated the cops the most and wanted to get famous by killing someone. In the scene when he was not able to shoot after that he realized how difficult and wrong is this. He was not a tough guy, his dreams were about him dancing and his attitude was because of the society. In the end, he kind of realized this and gave up with the gun. But as it is said it matters how you land. And he landed dead.

As well as Vinz dying pointlessly regardless of his goals to make a huge statement, even Hubert was drawn into violent actions that he didn't want. I felt that the analogy refers to the inevitability of their outcomes, and that no matter what they would like to happen their outcome is already decided because of the situation they are born into.
